Hardware Flow
Control (hardware
handshaking)
By definition, hardware handshaking is performed when two programs
manipulate RS-232 control pins-DTR, DSR, RTS, and CTS to achieve
a hardware-based form of flow control. In DTR/DSR handshaking, the
sender asserts DTR (Data Terminal Ready) before sending the first
character in a stream of data and waits for DSR (Data Set Ready) to
be asserted in return. RTS/CTS handshaking is similar, but uses the
Request To Send and Clear To Send pins rather than Data Terminal
Ready. In either case, the sender delays transmitting data until the
receiver is ready.
