Where is the COM Port in Windows 7?

If you want to use your USB device with your PC, you’ll need to locate the COM Port on your computer. This port is used by ham radio operators and a wide variety of legacy applications. Unfortunately, Windows doesn’t automatically assign it a COM port number; it might assign a higher one if it detects a device. To fix this problem, you’ll need to open the Command Prompt as an administrator.

COM ports have a number between one and 255. Each port is assigned to a particular device. The ports are assigned a use-by-date, so the number you see now is not necessarily the one that’s actually in use. COM ports higher than nine may have problems with some legacy software. Some adapters reserve up to thirty ports. If your PC has more than one COM port, the COM ports on your PC may be used by multiple devices.

Using the Device Manager, you can reassign a COM port to another device. However, you must make sure there is a COM port number free on your PC before you attempt to reassign it. This can be done by opening the Device Manager and selecting COM Port Number in the list. You may be prompted that the port number you selected has already been assigned. If that’s the case, try changing the device’s COM port number instead.

Next, open the System Supervisor window and find the Multi-port serial adapter. Click on the Properties hyperlink. In the Port Setting tab, change the quantity to the COM port you want to use.

If the COM port is not present, you may need to manually add it again. If you have a backup of the registry key, you should be able to restore your COM port configuration.

How Do I Make a COM Port Available?

To make a COM port available to another device, Windows users need to reassign the COM port. This process is done in Device Manager and requires a free COM port.

In Device Manager, you can find the communication port (COM1) and the serial port (COM2). These two devices will be listed as a good “communication port” in Device Manager.

You can also click “Remove Devices” to remove the devices.

Once you have done that, you can try the initial loopback test to see if your COM port is still working. This test sends a message to the device and receives it back, but only if the COM port is available. To do this, you need a serial cable with the pins and holes cut to a smaller length. Moreover, you need to run Device Manager as an administrator and choose the “Show Hidden Help” option. This will give you a list of all unused COM ports.
