How to Enable COM Port in Windows 10

In the following steps, we’ll go through the process of enabling a COM port on a Windows 10 machine. This will involve accessing the Device Manager, modifying port settings, and ensuring your system recognizes the port.

Step 1: Open the Device Manager

First, right-click on the Start button and select "Device Manager" from the context menu.

Device Manager is your go-to tool for managing hardware and drivers on your computer. It displays all the connected devices and allows you to configure them.

Step 2: Expand the Ports Section

Once in Device Manager, find the "Ports (COM & LPT)" section and click the small arrow next to it.

This section shows you all the available COM ports. If you don’t see it, it means no COM ports are currently recognized by your system.

Step 3: Right-click on a COM Port

Right-click on any of the listed COM ports and select "Properties" from the dropdown menu.

The Properties window gives you detailed information about the selected port and allows you to adjust its settings.

Step 4: Navigate to Port Settings

In the Properties window, go to the "Port Settings" tab and click on "Advanced".

Here you can change various settings related to the COM port, such as baud rate, data bits, and more.

Step 5: Change the COM Port Number

In the Advanced Settings, you can change the COM Port number if needed. Click "OK" to save the changes.

Changing the port number can help resolve conflicts with other devices and ensure smooth operation.

Step 6: Confirm and Close

After making your changes, click "OK" to close the Properties window and then close Device Manager.

Your changes will be saved, and the COM port should now be enabled and ready for use.

After completing these steps, your COM port will be enabled, and your computer should recognize it without any issues. This means you can now connect external devices that use COM ports and configure them as needed.
