[Xastir] Xastir remote TNC solution

[Mike Fenske]

Under windows, I have used a program called serproxy and connected to it 
with remserial from my linux box. This allows me to make use of an 
unused serial port on my windows computer for my X-10 controller and 
control it via my linux computer.

A windows binary for serproxy is available here: 
http://www.lspace.nildram.co.uk/freeware.html

Looks like source code is also available for linux version.
