For sure, flow control is key also. I noticed that the TNC was a mismatch with this Model 100, as my PC and other rig have no issues, no garbled characters, same baud rate — if I hit it hard with a large chunk of text, the M100 drops some chars, but it does not get garbled (odd ASCII chars). So, time to dig out the scope and probe around to visualize that mismatch between the TNC and the M100.
I’m glad to hear others use the M100 with TNCs etc. 73, N1UGK > On Jul 10, 2023, at 7:02 AM, Brian Brindle <bbrin...@gmail.com> wrote: > > Hey Jesse - congrats on getting the model T!
