So the program acts as a software protocol analyzer in this mode. Very low-cost systems, such as some early home computers , would instead use the CPU to send the data through an output pin, using the bit banging technique. It allows two legacy serial applications to communicate using created ports instead of using named pipes or any other modern inter-process communication mechanisms.

Some miniaturized electronics, particularly graphing calculators and hand-held amateur and two-way radio equipment, have serial ports using a phone connector , usually the smaller 2. You can also apply Capture options during the ongoing monitoring process with this RS monitoring software.
