Try using minicom to send control commands to the radio or TNC
(depending on which mode it's in)

A more basic test would be to short pins 2 and 3 on the serial
connector, set minicom to no local echo and see if what you type shows
up on the screen (or if local echo is enabled, you should get double
what you type).
