<communications> A technique for regulating the flow of data across an interface by means of signals carried on separate wires.
A common example is the RTS (Request to Send) and CTS (Clear to Send) signals on an EIA-232 serial line.
The alternative, software handshaking, uses two special characters inserted into the data stream to carry the same information.
