  The code for "listen" would be another good source, or perhaps the
  output of it could be piped directly into his app that fill the
  database.  Listen already decodes the packets into human-readable
  format.

  Also, isn't there a program somewhere that simulates a command-mode
  TNC interface from an AX.25 KISS port?  That might be all he needs,
  then his code just thinks it's talking to a serial TNC.
