1200bps is the most a standard radio can handle. Ie: any off the shelf ham 
radio rig.
Basic example is just connecting the tnc (modem) to the mic line/audio out 
line.

To go to for example, 9600bps. The radio needs to support that mode and the 
connection bypasses the standard audo processing
systems.
