Spence,

I did all you proposed, and it did go well. Things reacted the way you demonstrated. Still no luck with the other programs like HamRadioDeluxe, FL-digi, FTBasicMMO, FTBCAT or WSJT-X. Just like before, Rats847 will connect, but has no feedback from the radio. Seems commands are understood by the radio and there is no duplex communication. The display CAT icon is still on, though.
