  Ummm, Bill... you mean the Navy had AX.25 protcol damn near 40
years before Bolt Beranek and Newman....?

  Now *Baudot* Teletype over radio...maybe, and I'd like to see that
document, since I love the "green keys" and run RTTY more than voice,
but AFAIK, the Tuscon Amateur Packet Radio club first transmitted
AX.25 over radio in the late 70s / early 80s, and did so only after
the advent of easily-available microprocessors to implement the
Packet Assembler/Disassembler function.
