ComPortInfo is a utility tool designed for Windows that provides detailed information about COM ports and their parameters. This standalone application, originally part of ComPortMan, offers users the ability to view COM ports and connection types in two distinct formats. It facilitates hardware management by enabling users to safely remove devices and restart them, provided the application is run with administrative privileges. Additionally, it allows for the resetting of USB ports across various Windows versions, enhancing device connectivity and functionality.

The program provides comprehensive details about each COM port, including the last application that accessed the port and its current state, which is crucial for troubleshooting. Users can view default port parameters and hardware capabilities, such as supported signals and data rates. This utility is particularly beneficial for technicians and advanced users who require precise control and information regarding their serial communication hardware.
