Hi Dave, Welcome. I'll just add that you should also check the baud rate on the TNC. Some TNCs have a set of DIP switches to set the baud rate. It needs to match the baud rate on your Model 102. And, while the PC/laptop was probably happy writing to the screen at 9600 baud and faster, the Model 102 might be happier at a slower baud rate. If you see it dropping characters, change both the TNC and Model 102 to a slower speed and/or enable flow control (either XON/XOFF or RTS/CTS depending on what your TNC supports). Douglas
