Monitor the serial ports in Windows and detect and display changes

Serial Port Change

Introduction

We've all been there; you have a bunch of USB-serial adapters and you have to figure out which serial port it is. Traditionally, I've done this by opening Device Manager, try to remember all the ports connected, unplug the device, and look for changes. There has to be a better way, so Serial Port Change to the rescue!

What it Does

This utility is simplicity itself. It is a command line tool that extracts a set of serial ports, then periodically looks for changes. If a port is added, it will return:

New serial port detected: COM12

If a port is removed, it will return:

Serial port removed: COM12

This process will end when the user types CTRL-C.

How to Run

There are a few ways to run the project. You can install it with Pip:

$ pip install serial-port-change

Then run it with the script (assuming the Python scripts path is in your global path)

$ serial_port_change

If you have Astral uv installed, you can also run it (without directly installing it) using uvx like:

uvx serial_port_change

Modifying

The project is built using the uv package manager, although it could be easily recasted to Poetry or some other package manager. There are also files to set up the project using PyCharm, although this isn't required.

It is also setup to use bump2version to control the version number. For instance, if the current revision is 1.2.3, you can execute

$ uvx bump2version minor

To upgrade to version 1.3.0. You can also vary the major and patch revision levels. Refer to the bump2version documentation for more information.
