XON/XOFF handshaking is a software-controlled protocol used in serial communication to control data flow between devices, typically over RS-232. It uses specific control characters (XON to resume transmission and XOFF to pause transmission) sent over the same data path used for data transmission, unlike hardware-controlled handshaking which uses separate lines/signals for flow control.
