Hola Mark,

Since tnc's talk X.25, I would start at
http://www.arrl.org/catalog/index.html, the catalog page of the Amateur
Radio Relay League. I would order the book Practical Packet Radio, by Stan
Horzepa.
We have done some applications in X.25 in parts from 16C54's to 16C74's and
they work great. The HDLC-style protocol is medium complex, but is designed
for networks that have RF as the physical layer. The code, however, belongs
to our clients and / or us.
