I was working on designing a surface mount PC board to build up a
bunch of Bob Ball's nifty $25 PIC-based TNCs together so every RACES
radio would have one built-in. . . and then read the source code and
discovered it doesn't do AX.25 connected mode!
Any suggestions for a TNC that:
- Is cheap enough I can afford to give away 20 of them,
- Is small enough to install inside a mobile radio,
- Is AX.25 connected mode capable,
- Is NOT KISS or APRS (UI) specific,
- Is NOT dependant on ANY PC interaction or support,
- Will digipeat.

The NO KISS specification I think eliminates the John Hansen products ?
He now lists these under the name Coastal ChipWorks - TNC X solution

You can also ask John of his thoughts (his designs are also PIC based)
His TNC-X boards are expandable via an expansion header that allows the
addition of "daughter boards".
