What is RS232 serial communication protocol?
RS-232 protocol RS232 is the first serial protocol used for connecting modems for telephony. It is also used in modem, mouse, and CNC (computed numerical computing) machines. You can connect only a single transmitter to a single receiver. It supports full duplex communication and allows baud rate up to 1Mbps. Cable length is limited to 50 feet.
