Have you researched Packet Radio? The modem used is normally called a TNC,
ot Terminal Node Controller. There are quite a few books out on the subject
and TNC's are available commercially from amatuer radio suppliers. I suspect
an altavista search would turn up a lot of information.

I have a unit made by Baycom that is as small as a DB25 connector.

Personally, I lost interest in Packet when I finally got Internet access...
