JMRI
From Rxtx
JMRI uses RXTX to connect to the serial ports on model railroad hardware.
JMRI was originally written to use the Sun javax.comm API, and still uses those classes. We moved to RXTX for platforms where the Sun implementation wasn't available, or wasn't reliable. Currently, we use RXTX for MacOS X, Linux, and certain flavors of Windows.
The source tree is available from SourceForge either via anonymous download or their CVS web browser.
