Serialenum is a simple utility to correctly enumerate all available and present serial ports on a given system. There are a number of ways to enumerate serial ports, but they are platform-specific and vary in effectiveness. Serialenum attempts to provide the best possible methods for each supported platform.

pip install serialenum

import serialenum

serialenum.enumerate()

The enumerate method will return a list of serial ports or a blank list, if none are found. If serial ports could not be enumerated, it will return None.

Script called serialenum can be used from command line

serialenum

It prints out all found serial ports, one per line.

1. Windows XP or later
2. Recent Linux 2.6+ kernels

The Windows implementation iterates over a registry key to ensure that usb-to-serial converters and oddly-named COM ports are discovered. This should work correctly on any modern version of Windows.

The Linux implementation uses /dev/serial to enumerate attached serialenum port devices. This avoids the fake ttyS devices typically present and also accounts for usb-to-serial converters.

• Add fallback support for older Linux systems
• Add support for more operating systems (testing help needed)
