One approach to your problem is known as packet radio, which is exactly
what you need -- digital data via radio.

You can find information on the hobby side of packet radio in
rec.radio.amateur.packet.

Several manufacturers make complete turn-key packet systems -- connect the
RS-232 cables and treat the "box" as an external modem, only the data is
transmitted by radio, not telephone.

I recommend this manufacturer:

PacComm Packet Radio systems, Inc.
4413 N. Hesperides St.
Tampa, FL  33614-7618
Voice: 813-874-2980
FAX:   813-872-8696
BBS:   813-874-3078

Internet:  76576.2003@compuserve.com



As I recall, PacComm's commercial units can respond to the "Hayes
Standard" AT Command Set, just like a modem.  This should help simplify
your project.

Good luck!
