When studying serial communication protocols, you may want to repeat the same command sequence sent to serial equipment.

How can our software help decode serial communication protocol? How can our serial software replace free Portmon?Īpart from Portmon, our software does not show low-level I/O requests but decodes them to a human-readable form. It didn't update for some time and may not work on modern versions of Windows. Portmon monitors Windows kernel-level I/O packets sent/received between serial port device drivers. You can use the RS232 monitor without any programming skills. The RS232 monitoring tool does not require special knowledge, and students and professionals can use it to test/debug/view serial communication. The program allows you to store the settings for each copy individually. Start several instances of our COM port sniffer and monitor communication with your peripheral devices simultaneously. Using the serial port sniffer mode, you can monitor serial port activity without any cables and additional hardware.
