Serial Port Monitor

We make extensive use of this software utility to monitor and log serial port traffic when testing third-party programs. It’s a great tool for troubleshooting serial protocols or reverse-engineering undocumented functions in software products.

I was looking for a lightweight app for incoming and outcoming data monitoring between Ant and COM port with a hardware device attached to it that communicates with the software.
Serial Port Monitor worked just fine for that purpose.

This terminal is very straight forward and useful for opening COM ports, monitoring ASCII data, and exporting the file.

This is a simple and straight forward monitoring SW that allows you to open COM ports, monitor, and export the data. It addresses my needs perfectly.

Serial Port Monitor is an essential tool for debugging and monitoring devices that use serial port.
I have used it for analyzing the data messages from Radon sensors.
