Quickly Identify Your USB to Serial Adapter’s COM Port
Determining which COM port Windows assigns to a USB-to-Serial adapter can be a frustrating and time-consuming task. Whether you're connecting an RS232, RS485, or another type of device, you often need to locate the assigned COM port before the device can be used properly.
The usual method?
You’d typically need to navigate through multiple menus:
Click Start
Go to Control Panel > Hardware and Sound > Device Manager
In Device Manager, expand the Ports (COM & LPT) section to see the assigned COM port.
