Try using DireWolf or the UZ7HO Soundmodem instead of the archaic 40-year-old 
hardware TNC2 device.  These  soundcard soft TNCs have infinitely better 
performance on weak marginal signals than legacy hardware --and-- present both 
AGWpe and KISS-over-IP interfaces to applications.  They also eliminate a box 
and the nearly half-amp @ 12VDC power drain of the TNC2.

Note that the UZ7HO Soundmodem is a Windows application (though I have heard it 
can be made to work in Linux with a Wine kludge). DireWolf is available in 
native versions for both Windows and Linux -- i.e. would be usable on the Pi.

If you really want to use the legacy MFJ-1274, replace it's MFJ firmware eproms 
with the final release of the generic TAPR TNC2 firmware (ver 1.1.9) which DOES 
have KISS mode.       I've put this in numerous MFJ TNC2 clones and it works 
just fine.
