I'm trying to remote an Elecraft W-2 wattmeter that has an RS232 interface. The DB9 connector has RTS/CTS looped toward what would normally be the computer. I am trying to extend this connection using the virtual port driver to a distant computer. It appears that the software on the computer wants to see a loop on RTS/CTS to provide flow control. (not sure of this yet).
I wonder if the Microbit Virtual Port Driver supports RTS and CTS?
