KD7NM near me has the same problem periodically.  Power-cycling the
TNC fixes it for him too.  He's running it in KISS mode with Xastir.
It's happened at least 2 or 3 times that I can recall, but seems to
take months to reappear.

It could be that a KISS frame END character gets missed or
corrupted, requiring a new KISS frame to come through to supply it,
but then that one gets stuck because of not enough framing
characters, awaiting the next packet to come through, etc.

It could also be a memory leak or counters overflowing and losing
track.  Could be all kinds of things.
