I clear my storage and I found old one TNC2modem.
All wires, power cable.
I connect it to my old laptop (TNC needs RS 9-pin). I can connect to modem vie putty or UI-View32.
Terminal show me firmware NORD><LINK by WB8DED.
but I can't send any frame to my radio. Software show sent frame, but tnc did'n transmit to TRX.
I know that is old equipment but will be nice to connect to radio and use it to APRS.
Anyone can help me to check this TNC, pls.
