Q: How to check which COM port I am using?

  • Windows System:

    • ①Check via Device Manager: Press Windows + R to open the "Run" dialog box. Type devmgmt.msc and press Enter to open Device Manager. Expand the "Ports (COM & LPT)" section. All COM ports and their current status will be listed here.
    • ②Check using Command Prompt: Open the Command Prompt (CMD), type the mode command, which will display status information for all COM ports.
    • ③Check Hardware Connection: If an external device is already connected to a COM port, the device typically occupies a port number. You can determine which port is being used by checking the connected hardware.
