Serial Port Monitor

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.

I had been looking for a method to have my JS application communicate to a PLC via the MODBUS RTU protocol. While I was able to communicate the PLC through MODBUS TCP protocol, I was unable to revise the code to function with the MODBUS RTU and so they have not been able to locate each other.

Multiple attempts to connect my PLC to the MODBUS RTU ended with time-out errors unless I rebooted the unit. Obviously, I was frustrated and desperate for a solution.

I eventually came across the Serial Port Monitor after trying dozens of options, including multiple MODBUS emulators, with no luck at all. I found that the Serial Port Monitor helped me analyze exactly where the COM port error was coming from and helped me figure out how to establish communication with MODBUS RTU.

This Serial Port Monitor also hosts a plethora of features that made other aspects of my javascript application more efficient. As a student ready to break into the field of software development, I’m glad that I found this professional SPM software that makes my future career easier and more efficient.
