Hi, I'm using Win 10 x64 machine. Have installed com0com tool and updated with signed driver from https://pete.akeo.ie/2011/07/com0com-signed-drivers.html Now am able to configure ports. But it is not reflecting in Ports (COM & LPT) and hence it is not working. COM 15 and COM 16 virtual ports are created; but not reflecting in Ports (COM & LPT). Please let me know if any commands are needed to add virtual ports in Ports (COM & LPT).
