RS 232 Port
Computers are normally equipped with a
serial port for
communications. This port type is usually
referred to as RS 232C, V.24N.28, or DIN
66 020. Signal coupling of the interface to
this port is achieved in DUPLEX operation
(data transfer is possible in both directions
at the same time, XON/XOFF
supported).
