Perhaps my posts are not all making it to the list?  There are in fact two 
things in this project.  The library level parsing and construction of APRS 
packets (and there is opentrac in there too), and the larger bit of code that 
was my initial work on a "modular" application system.

The javax.comm business is a funny thing.  I have support for javax.comm.  You 
just have to get the implementation for the platform that you want to run code on.

The RxTx project is the current main stream provider of implementations of this API.
