Serial Port Monitor in Linux OS
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:
Serial Monitor
This serial port monitor for Linux is a plugin that lets you display all serial port activity initiated by other applications.
Pros:
- 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.
