I think I'm getting there.
The problems (outside of writing the code) seem to be:
1) RF in the serial line. Use ferrite chokes about 14" from the HT.
2) Battery problems:
2a) The Kenwood's serial port seems to go sour with low batteries. You can command the TNC (MON ON), but incoming strings are sometimes lost.
2b) The HP-50G powers the serial port adapter, and it runs the batteries down pretty quickly. This can be cured by running power into it via the USB port adapter. I have to look into this...
I don't know if it'll be of use to the PIC people, but I'll be posting the UserRPL code for it pretty soon. It may need a few more if-then-else-end's. Please don't nit-pick the code. It's a hack job, but it works.
