  It sounds to me like you've acquired a TNC-200 which is in KISS mode.

You might have a standard ROM, in which there is defined an 'escape 
sequence' which can be typed into a terminal program which will give you a 
CMD: prompt, where you can enter KISS OFF, then reboot, and you should get 
a more readable signon message and a CMD: prompt.  Unfortunately, my 
TNC-200 manual is out in the shack, and I'm still in my bathrobe this 
morning.  Mebbe somebody else knows the escape sequence from memory.

You might have a dedicated KISS ROM, in which case, I'd define it to 
xastir as a kiss tnc, and see if xastir can digest the packets.
