LINUX + WINDOWS

Hello, I'm new on this subject. I'm not sure if I've understood everything.

Is it now posible to write an application using RXTX, and then run it on Linux AND Windows?

Thanks

Linux + WINDOWS

RXTX is tested on Linux, Solaris and Windows. The package is also tested by the Mac OSX community.

Other systems should work but are not tested as much.

So the answer to your question is yes.

Maximum baud rate

I need to talk 4Mbit/s between a Java application and a CDC virtual serial port (COM4). The Windows driver supports the 4Mbit/s speed.

Can I open a serial port with RXTX with higher speed than 115kbps?

Mailing List

I highly recommend you join the mailing-list, since you will get more answers there.

Lock Files and serialPort.close()

Hi,

I am running into the lock file permission problems, even though I've added my user to the uucp group. using Debian Sarge.

when I run my app as root, it clears out any stake lock files, but when it tries to close the serialPort with serialPort.close() it just stalls.

the next time a scheduled read happens, I see this error:

RXTX fhs_lock() Error: creating lock file: /var/lock/LCK..ttyS0: File exists

which makes sense. but why can't I close the serial port when running even as root?

thanks - trying to port from javax.comm, which does work for this stuff (but maybe not for other issues..)

thanks, John
