Serial Com Port Monitor monitors, displays, logs, and analyzes all activity happening in RS232/422/485 COM ports in your system, helping solve debugging issues related to computer connections with peripheral devices via COM port.

This tool enables you to monitor all data sent to and received from serial RS232/422/485 ports, as well as all events sent to a port by an application and the status of those events. It offers different types of monitored data representation, making it easy to keep track of everything happening on the serial port.
Serial Port Monitor connects to a COM port opened by any application or hardware and starts monitoring it in real-time. This means that all the data passing through the monitored port will show up in the tool, allowing you to immediately track down any issues.
Moreover, Serial Com Port Monitor enables you to intercept and record all serial input/output control codes (IOCTLs), tracking their full details and parameters. You can redirect all monitoring data to a defined file or copy it to the clipboard for further analysis.
One of the best features of Serial Port Monitor is the ability to choose monitoring filters, saving you time and enabling you to track down only specific events that you're interested in. Additionally, you can modify serial port settings, including stopbits, flow control, parity control, data bits, and highlighting, during a session to ensure you have complete control over the port's behavior.
Serial Com Port Monitor also provides the ability to send data of various formats, such as string, binary, and hexadecimal, allowing you to simulate real-world scenarios for testing purposes.
In conclusion, if you're looking for a reliable and professional serial port monitoring tool that can help you analyze, track, log, and troubleshoot your serial communication, Serial Com Port Monitor is the best choice.
