How do I know the COM port number?

The COM port to which the USB converter is connected may also be displayed in Windows 7:

  2. There, select "Hardware and Sound" select
  3. Under "Devices and Printers" you can access the Device Manager
  4. In the "Ports (COM & LPT)" you will find the assigned COM port.
