Serial Port Monitor is a utility that sits in your notification tray and monitors the serial ports on your computer. When a port is added or removed, a notification is shown containing the COM port name, allowing you to easily keep track of what’s been plugged in and out. This saves having to navigate to Device Manager to figure out what’s been plugged in.


Serial Port Monitor can be downloaded from the project’s SourceForge page.


If you have any problems, please post a message on the SourceForge Serial Port Monitor Forums.

  1. Hello,
    I have installed your tool under Windows 8.1 Prof. Edition and wind an Icon in the System Tray. I see the available ComPorts but I do not see any window with the data traffic on the port. What do I wrong?

    1. Hi Svens,

      I think you may be confusing another program with the same name. This software is designed just to show the COM ports that are plugged in to the computer. It doesn’t actually monitor the traffic passing through.
