Some users may use Linux systems to read serial ports and monitor their system’s serial activity. We have some solutions that will run on the Linux OS:
This serial port monitor for Linux is a plugin that lets you display all serial port activity initiated by other applications.
- You can see the actual data flow as well as events such as the opening and closing of ports and changes in the control and status lines
- It intercepts the calls between a serial port driver and an application enabling direct monitoring of the serial I/O
You can evaluate the plugin for free but continued use requires a license that will cost you $95.

- the author has not needed to make updates to the code since 2011 but continues to support the program;
- component of the Debian OS.
- it is a command line tool that does not present a user-friendly interface.
