Serial (or COM) port is an interface for serial communication.Through this interface information transfers in or out one bit at a time. Historically data was transferred through serial ports to devices such as modems, terminals, etc. With the invention of USB, Ethernet, FireWire serial ports became less used. However they are an important part of industrial automation systems, network-enabling and lab equipment, scientific instruments, and more.
It is known that Windows OS does not feature any specific instruments for COM port monitoring, so the search has to be performed. But no worries, there is a great software to monitor, log, and analyze serial port activity.
Serial Port Monitor is developed by Eltima Software to offer exceptional serial port analysis. It offers monitoring, keeping logs, laying them out in a comprehensive manner. This software offers a reliable way to troubleshoot while developing your own application or driver, testing and optimizing serial devices, and more.
Serial Port Monitor offers you:
1. Connection to a COM port opened by a different application to monitor it right away. See all data received by the COM port in real time and track down any possible issue immediately.
2. Monitoring of several COM ports at a time. Analyze several remote COM ports activity during one session – two, three or more – concurrently. All data is conveniently recorded in a single log on a first-in first-out basis.
3. Data display in a table, dump, line, and terminal modes. Customizable filters help you monitor only events you are really interested in.
4. Data emulation. Use Terminal mode feature to emulate sending data to serial device from a monitored application. Various formats (string, binary, octal, decimal, hexadecimal, mixed) are supported.
