Tracker and YAAC

[arizonajon1]

Maybe I asked this before, but I'd like to add the LilyGO Supreme tracker to my YAAC mobile running W11 via USB serial. It's obvious that packet information is getting to YAAC, I can see it here in the "TEST PORT" function of YAAC, but only when the Enable Port is left unchecked.

but clearly something is misconfigured since I only see this information if the "Enable Port" is not checked. If I check "Enable Port" then no packets ever show up at YAAC, and the TEST PORT window never shows packet data from received packets. This is what I get in the TEST PORT window if Enable Port is checked:

Is there a way that I can enable TNC functionality without having to use BT or BLE? MY truck computer has BT and BLE in it but I don't think it has a bluetooth serial port profile, it only recognizes that there's a LilyGO device on BT.
