Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Hi,

I need to use SMSLib(JSMSEngine) on my FreeBSD, so I have to install RxTx first.
But when I tried to install RxTx (port or package), the system output
some message and stop.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Doug,

Our 1-Wire API uses RXTX to talk to 1-Wire sensors.  We have temperature,
humidity, and A-to-D sensors available.

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <7d2b46e50604250509o72de8bddk1e1b955a3617d8f9@mail.gmail.com>

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <7d2b46e50604250509o72de8bddk1e1b955a3617d8f9@mail.gmail.com>

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

I'm sorry if this is a dumb question, but I didn't find the answer in

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

unzip and ./configure

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Hi,

I need to use SMSLib(JSMSEngine) on my FreeBSD, so I have to install RxTx first.
But when I tried to install RxTx (port or package), the system output
some message and stop.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Doug,

Our 1-Wire API uses RXTX to talk to 1-Wire sensors.  We have temperature,
humidity, and A-to-D sensors available.

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <7d2b46e50604250509o72de8bddk1e1b955a3617d8f9@mail.gmail.com>

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <7d2b46e50604250509o72de8bddk1e1b955a3617d8f9@mail.gmail.com>

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

I'm sorry if this is a dumb question, but I didn't find the answer in

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

unzip and ./configure

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Hi,

I need to use SMSLib(JSMSEngine) on my FreeBSD, so I have to install RxTx first.
But when I tried to install RxTx (port or package), the system output
some message and stop.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Doug,

Our 1-Wire API uses RXTX to talk to 1-Wire sensors.  We have temperature,
humidity, and A-to-D sensors available.

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <7d2b46e50604250509o72de8bddk1e1b955a3617d8f9@mail.gmail.com>

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <7d2b46e50604250509o72de8bddk1e1b955a3617d8f9@mail.gmail.com>

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

I'm sorry if this is a dumb question, but I didn't find the answer in

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

unzip and ./configure

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Hi,

I need to use SMSLib(JSMSEngine) on my FreeBSD, so I have to install RxTx first.
But when I tried to install RxTx (port or package), the system output
some message and stop.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Doug,

Our 1-Wire API uses RXTX to talk to 1-Wire sensors.  We have temperature,
humidity, and A-to-D sensors available.

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <7d2b46e50604250509o72de8bddk1e1b955a3617d8f9@mail.gmail.com>

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <7d2b46e50604250509o72de8bddk1e1b955a3617d8f9@mail.gmail.com>

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

I'm sorry if this is a dumb question, but I didn't find the answer in

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

unzip and ./configure

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Hi,

I need to use SMSLib(JSMSEngine) on my FreeBSD, so I have to install RxTx first.
But when I tried to install RxTx (port or package), the system output
some message and stop.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure

And I couldn't continue the process.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

Hi,

I tried to get
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7.zip and
ftp://ftp.qbang.org/pub/rxtx/rxtx-2.1-7r2.zip
unzip and ./configure
but after I made the source, the output was return:
====================================
root at David /usr/local/tmp/rxtx-2.1-7#make
Error expanding embedded variable.
====================================
And I couldn't continue the process.
thanks...

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in

Any help on how to solve this problem would be immensely appreciated.

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Doug,

Our 1-Wire API uses RXTX to talk to 1-Wire sensors.  We have temperature,
humidity, and A-to-D sensors available.

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......

   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <7d2b46e50604250509o72de8bddk1e1b955a3617d8f9@mail.gmail.com>

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <7d2b46e50604250509o72de8bddk1e1b955a3617d8f9@mail.gmail.com>

Hi there,

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

I am trying to access a datacard I have using RXTX and the CommApi. During
runtime I get this error

Exception in thread "main" java.langUnsatisfiedLinkError: no rxtxSerial in
java.library.path
   ......
   ......
   ......
   ......

Any help on how to solve this problem would be immensely appreciated.

Thanks

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Subject: [Rxtx] How to read from RxTx parallel port in Win XP
Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

I'm sorry if this is a dumb question, but I didn't find the answer in

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

Is anyone using Locks for the serial ports?
The Doug Lea code appears to have made it into
the concurrent package, so that we can have ReadWriteLock
built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!

Have you tried compiling rxtx 2.1-7?  If you give me the output on or 
off the list, I can probably fix the compile error easily.  rxtx compies 
on solaris for instance.  It wont be hard to fix.

libpthread is part of glibc.  I guess you are using a linux compatability 
layer?  More interesting would be getting the native bsd working again. 
I'm not aware of why its been marked unable to compile.  Thats not from 
rxtx.

Hi Doug

I tried to push lockfiles because its the right thing to do for 
standards like the FHS.  I still think rxtx should use lockfiles and if 
the fight is to be had it should be done in the standards.

But many companies ship rxtx with locks disabled.

It is a mess and wasn't thought out in advance.  Do you have an idea?
I need to read about ReadWriteLock.   As you mention this is a big mess 
with versions even if done right.

WHy not apply a little OO in the C part of RXTX? Define an interface
like the following:

extern int lock(); /* returns false if lock fails */
extern void unlock(); /* possibly called at exit */

next implement a few, small, .so files that implement different locking
mechanisms (the OO jargon is 'strategies' here). Set an environment
variable that tells which locking mechanism needs to be used, e.g.

set LOCKING_MECHANISM macOS
set LOCKING_MECHANISM file_locking

etc. etc. If this environment variable is not set, pick an applicable
default value, say file_locking.

The core rxtx package checks this environment variable, dlopens the
corresponding .so file, dlsyms for the 'lock' function and voila.

Of course this simple interface can be pooped up with additional
functionality of course.

kind regards,

Jos

Message-ID: <0BC54F4063F4F240A3C30F67E40E380703EF4376@cacexc09.americas.cpqcorp.net>

I'm sorry if this is a dumb question, but I didn't find the answer in
the archives.

I'm using the RxTx binaries for Windows on a reasonably current notebook
PC running Windows XP.  I can send stuff to a printer on the parallel
port (LPT1), but I can't get anything back.

I wrote a class that has the methods listed below.  I write some data to
the printer with the "write" method and then try to read a response
using the "read" method, but I never get any data.  I'd greatly
appreciate any help you can give!

built into the CORE jdk1.5.

The Comm API needs this type of thing, right?

Of course, none of this will work under JDK1.4, which is
a bit of a stinky mess.

Thanks!
