Well, perhaps you could use 9600 baud TNCs?  Not as popular of course, but 
they are out there.

David,

Even without the AX.25 headers, the TNC frames its own packets.
Unfortunately, TNCs buffer the packets so the delay is horrible. And the
throughput is somewhat less than 1200 Baud, so long transmissions
accumulate an additional delay. Still, it's useful for a demo.

     Thanks

     Bruce
