I found with the 1270b and kiss only image was the only way to go as a igate running aprx.

Just to pick up on one of Tony's points, the KISS implementation in the standard TNC2 EPROM (including the MFJ1270B) is BADLY broken. It has horrendous timing issues and is best avoided. If you want KISS in a MFJ1270B, burn a KISS only EPROM. You'll have a TNC that is permanently in KISS but without the timing issues. I can supply a KISS only image if required.
Some issues with the standard EPROM include not transmitting data, transmitting data over an incoming signal and not passing data to the computer. It's hair tearing stuff when you get caught by it and probably what gave KISS a bad name for timing in the early days of KISS.
