I have a Dell Optiplex 7020 running Windows 10 with one physical serial port. I checked the device manager and found that it only detects one COM port (COM1), while in other machine running windows XP/7/8 I would see up to 7 or more available COM ports (COM2,COM3...,COM7) :
I also check via powershell :
I would like to connect another device with a serial interface but the problem is the COM1 is already being used, while I cant find another COM ports.
Is it the limitation on the machine and/or windows 10? Is there a way to manually add another COM ports (COM2,COM3,..COM7) to my machine ?
