Using a Yaesu FT-991A with USB drivers installed (and both are working OK with WSJT-X, enhanced CAT port com 9 and normal port com 8), on Digipan 2 I can receive OK with rec and transmit set to virtual sound card in the Yaesu seen thru (I'm guessing) com 8, but PTT apparently uses com 9 port. When I try to configure PTT to com 9, I get msg: "error opening com 9", and PTT does not work when I try to transmit from Digipan. I've pretty much tried all of settings for the port from control panel. No help. Also tried using the enhanced port com 8. No error then but no matter settings of RTS/DTR there is still no PTT function. Any ideas? TNX
