Serial Port Monitor
COM port monitoring software
Serial Port Monitor is a professional and powerful system utility for RS232/422/485 ports monitoring. COM monitor displays, logs and analyzes all serial port activity in a system. This is an ideal way to track down problems that may occur during application or driver development, testing and optimization of serial devices, etc.
This product also offers advanced filtering and search, professional built-in terminal and data exporting options, user-friendly and flexible interface among its key advantages. It is a completely software solution, you don't need any additional hardware to use it.
Serial Port Monitor can be purchased as a Standard or Professional Edition.
With Serial Port Monitor you can
Analyze serial port activitySerial Monitor can connect even to a COM port already opened by any application to start monitoring it right away. All data going through the monitored port will show up in various views in our monitoring tool. Table view packets feature the transcript hint from Line view. Everything is captured in real-time, so you can track down problems immediately. The synchronized highlighting of similar IRPs in different views is especially convenient for comparison purposes.
Moreover, you can redirect all monitoring data to the specified file or you can copy all recorded data to clipboard. COM Port Monitor gives you the ability to intercept and record all serial input/output control codes (IOCTLs), tracking their full details and parameters. You can save any monitoring session and load it next time whenever you need it.
Monitor several ports within one sessionThis software has a unique functionality of monitoring several COM-ports simultaneously. Now you can collect data on how apps interact with two or more ports and a few devices concurrently within one session. Data received and sent during monitoring will be presented (recorded) in a single log on a first-in first-out basis; this makes it more convenient for analysis.
Read captured data in different waysYou can view data in all 4 monitoring views at the same time: table, line, dump or terminal mode. Dump view can display binary, ASCII data, as well as port settings. COM Monitor lets you choose monitoring filters, thus saving your time and letting you track down only those events you are interested in. You can also apply Capture options during the ongoing monitoring process.
Emulate data sending to serial deviceYou can send data in various formats (string, binary, octal, decimal, hexadecimal, mixed) to monitored serial port as if it was sent on behalf of monitored application using terminal mode feature of Serial Monitor. Thus you can follow the reaction of the monitored serial device to some special commands and data.
Full support for Modbus RTU and Modbus ASCII protocolsCOM Port Monitor will help read and analyze Modbus data with its new efficient filters. With the help of our software you can easily establish connection with RS485/422/232 devices and analyze their data as well.
Playback and session comparisonSerial Port Monitor offers a unique session playback possibility - you can send data received from the app to the serial port again. This way you can review port’s behavior on receipt of the same data for more precise monitoring results. Also you can compare sessions with automatic display of differences between them.
