Alternative Method to Check COM Ports in Windows 11


Windows 11 native tools are highly reliable with basic COM port checks, yet they have insufficient capacity for advanced checking that involves virtual COM ports and debugging tools.

For this reason, a third party can be beneficial, especially if:

  • Your PC lacks physical COM ports but needs serial communication.
  • You need to create or simulate virtual COM ports for testing.
  • You work with USB-to-serial adapters or require advanced troubleshooting.

In this section, we discuss how to enable COM ports in Windows 11 using external tools.

Virtual Serial Port Driver



Virtual Serial Port Driver (VSPD) enables users to create virtual COM ports that simulate physical serial port connections.

This application is highly useful with software that requires serial port communication but lacks access to physical ports.
