There are numerous possibilities for projects that involve serial communication.
Java is an excellent language for putting GUI apps together.  Well have fun.  
Send back stories. 

Copies of the latest RXTX will be on http://www.rxtx.org/download
The primary source for information/support is http://www.rxtx.org.

This is a native lib for jdk 1.1.* and newer.  If you find changes required
for different platforms or OS's please pass them back this way so we may share
it with others.  Credit will be given unless one specifically requests no 
credit.

We chopped rxtx out of my program and tried to put a small example together.  
There is plenty of room for configurability, safe guarding and error reporting.
If you have some time please contribute some improvements.

We are interested in sharing this code in hopes that a more versatile lib may
be developed and released with minimal restrictions.  Please send any patches 
back my way if you like.

If you are interested in using rxtx for things like RS485, I2C or raw IO Please
get the latest CVS version.  Some work has been done for each of them.  The
latest development version is a stand alone implementation of CommAPI.

For bug reports please follow the directions in INSTALL
