Step 4: Right-click on the COM Port

This will open a new window with details about the selected COM port. Here you can find more specific information about the port’s functionality and settings.
Step 5: Check Port Details
Navigate to the "Port Settings" tab and click on "Advanced."
This tab will give you additional settings and information about the port. It’s useful if you need to change the COM port number or other settings.
After completing these steps, you’ll have a clear view of which COM ports are active and their details. This information can be very useful, especially when troubleshooting hardware connections or configuring new devices.
