[Elecraft] band data from the RS232 port while using the USB cable?

[Steve Steltzer]

Brand new to the K3S. Is there a way to get band data to control an Acom amp on the RS232 port while using the USB cable? I had a lot of trouble with Win10 assigning the radio to ports already in use when I tried using the RS232 port. Going in and manually changing the port number in Device Manager didn't work. Finally got it working using the USB cable and I really don't want to go through all that hassle again to try and get PC comms working using the RS232 port. Apparently when you select USB in the menu, it shuts off the RS232 port?
