VarAC - FM discussion forum

Hi everyone, I am using the command set attached below (as received from Irad) for CAT control of the IC-821H but I get no responce from the radio. RTS PTT is working. Any suggestions how to fix it?

CAT from FT-8 works flawlessly using the same cabling-interface, port numbers and 9600 speed.
