I wanted to follow up with this issue - As it turns out, the TNC itself seems to be the culprit, at least with the M100. Even small text strings get garbled, with software flow control enabled on both sides. That TNC works fine with a PC, just not the M100. Next time I have the scope out, I’ll take a look at the line and compare, and work back into the M100 as needed out of curiosity.
Another TNC I recently acquired works just fine at 9600 baud. The backpack drive also works without an issue on this M100. All is well. > On Jul 19, 2023, at 8:14 PM, John R.
