There are libraries for packet parsing for a few languages (e.g. libfap).
You can connect to xastir's server port with your program and receive
messages, then take actions based on your parsing.

If your linux computer is a pi (or something similar with GPIO) you can
probably go directly to an IO pin from your program.   If it's a typical
desktop, you can hook up an arduino and pass messages from your program to
the arduino and command actions that way.
