Why COM ports and monitoring them is important

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.
