Serial Port Tester - Version 7.0 Serial Port Tester is a professional software tool that enables you to conduct serial port tests on all of your system's RS232/422/485 COM ports. All of our system's serial port activity can be monitored and displayed as well as being logged and analyzed. You can test multiple com ports at once and use the tool to compare the sessions. Debugging RS232 ports as well as all devices using the port can be accomplished with the assistance of Serial Port Monitor. Data transmission between any Windows application and serial devices can be easily monitored using this tool. Serial Port Monitor can also assist with debugging connection issues between your computer's COM port and peripheral devices such as modems, mini-ATS, projectors and any other connected devices. This application also helps resolve connection problems between serial (RS232/422/485) data communication control networks and any attached device. In addition to enabling you to test your serial ports, any software or hardware device working with that port can also be monitored. Complete details and parameters from all serial input.output control codes (IOCTLs) can be intercepted and tracked, making it possible to analyze, debug and tune your system's serial connections. All COM port types, including standard onboard ports, SERIAL-via-USB adapters and extension board ports are fully supported by the Serial Port Monitor application.
