The port probably has an atypical device name that needs to be added to 
RXTXCommDriver.java.

You can add the port to the list and recompile just the java files to 
generate a new jar and it should work.  It is also possible to override 
port names with properties.

A way to test your port without doing any of this is to create a symbolic 
link from the device file to /dev/ttyS32 for instance.  RXTX should detect 
the port as /dev/ttyS* are enumerated.
