What is a serial port communications protocol?
2018-11-29 09:37:31

Serial port communications indicate that a serial interface exchanges data by bit. Although the serial port communications mode is slower than the parallel communications mode in which data is exchanged by byte, a serial interface can use a link to send data and use another link to receive data at the same time. Common serial port communications protocols include RS-232, RS-422, and RS-485.
