hardware handshaking

hardware handshaking

(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.

RS-232 ports, and in particular those on older devices, use hardware handshaking signals such as Ready to Send or Clear to Send.
If the device uses any type of hardware handshaking (aka RTS/CTS or DTR/DSR flow control), then these lines must be present in the cable.
The PacketMaker stream in Figure 4 shows the process for disabling hardware handshaking and inserting user-defined handshakes.
The cost-optimized single-chip baseband IC incorporates a link controller with an integrated PCM interface, UART support for both software or hardware handshaking, and integrated program ROM.
The three 8-b digital I/O ports can be configured as inputs or outputs, and each port supports hardware handshaking, strobe I/O, and bidirectional protocols.
