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.

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)
