Serial Port Monitor

What Serial Port Monitor customers say

A great tool!

November 5, 2026

I build a DIY home cockpit and use Arduinos to control various inputs/outputs of the cockpit. I wrote my own software for the data transfer between the flight simulation on the PC and the Arduinos. For me, the Serial Port Monitor is now an important tool for troubleshooting and improving the software in my home cockpit.

Reliable app

As an electronics technician, Serial Port Monitor has been a go-to tool for troubleshooting communication issues between embedded systems. I frequently use it to track data flowing through serial ports, ensuring that signals are transmitted correctly between devices. The software is straightforward, and I’ve found the interface to be very user-friendly. The log files are easy to analyze, which saves me time when diagnosing issues. However, when I work with large volumes of data, there is sometimes a slight delay, but it’s not frequent enough to cause any major disruptions. Overall, it’s an essential tool for anyone working with serial communication in electronics.

Helpful for debugging serial connections

October 19, 2026

I use Serial Port Monitor mainly to troubleshoot communication between Windows applications and serial devices. Being able to see the data going in both directions makes it much easier to figure out where something goes wrong. The HEX view is especially useful when working with binary data. It does what I need without making the process overly complicated.

Good serial port analyzer tool

October 15, 2026

As a software developer working with IoT devices, I regularly use Serial Port Monitor to analyze communication between devices and our server. The real-time monitoring and logging features are fantastic—allowing me to capture detailed data from every serial interaction. One of the things I love most is the software’s ability to log data over extended periods, which is extremely useful for debugging intermittent communication problems. The only minor issue I had was that sometimes the software doesn’t automatically detect the ports on startup, requiring me to manually configure them. Once I did that, everything worked perfectly, and it’s been smooth sailing ever since. I would definitely recommend this tool to other developers working with serial connections.

Helped me upgrade my family's farming software!

September 21, 2026

I originally got the free trial to use to try and sniff a communication port coming from chicken house controllers. I wanted to know when ALARMs were triggered and the software was so old that it could display it on its GUI but did not integrate into texting or email messages. The software worked great and I was able to snoop on the port that was already being used by the original software which most products do not support or allow.

I am now working on reverse engineering the protocol to be able to send texts on ALARMs which is a better alternative to our current relay/sensaphone approach. This software is really handy and makes working with serial communication based hardware a breeze!
