How to Check Com Port in Windows 10?

The first step in checking the status of a communication port in Windows 10 is to open the Device Manager. The Device Manager can be accessed by searching for it in the Windows search bar or by going to Control Panel > Hardware and Sound > Devices and Printers.

Once the Device Manager is open, users can then expand the “Ports (COM & LPT)” section to view the status of the communication ports. The next step is to check the status of the communication port. The status of the communication port can be determined by looking at the icon beside the port.

A green icon indicates that the port is working properly, while a yellow icon indicates that the port is having issues. If the port is having issues, users can try to resolve the issue by uninstalling and reinstalling the device.

Using the Command Prompt

In addition to checking the status of the communication port through the Device Manager, users can also use the Command Prompt to check the status of the port.

To do this, users need to open the Command Prompt and type in the command “wmic path Win32_SerialPort”. This will display a list of the communication ports and their status.

Using Third-Party Software

Finally, users can also check the status of the communication port using third-party software. There are a number of software programs available that can be used to check the status of the port.

Troubleshooting

If the communication port is having issues, users can try to troubleshoot the issue. The first step is to check the connections between the computer and the device.

Make sure that the cable is securely connected to both the computer and the device. If the connection is not secure, then the port will not work properly.

Checking the Drivers

The next step is to check the drivers of the device. If the device is not properly installed, then it will not be able to communicate with the computer.

To check the drivers, users can go to the manufacturer's website and download the latest version of the driver. Once the driver is installed, the communication port should be able to work properly.

Resetting the Port

If the communication port is still not working properly, users can try to reset the port. To do this, users can open the Device Manager, right-click on the port, and select the “Disable” option.

Once the port is disabled, users can then right-click on the port again and select the “Enable” option. This should reset the port and allow it to work properly.
