When the USB interface was introduced, serial ports were dislodged, remaining mainly in the industrial sector.

Why might one need to capture serial port data from a COM port?
Tracking down a problem that might appear during the development stage of the custom application or a driver for a COM device and dealing with it in the shortest time would not be possible without the ability to capture serial data and store it for the later use and analysis.
Unfortunately, Windows does not offer any built into the OS utilities that would help achieve this. So, one would need to resort to help of a specialized serial data capture software, such as Serial Port Monitor that would assist with capturing and examining the data exchange between RS232 devices and Windows applications.
