A serial port on the rear panel of a
PCIn computing, a serial port is an interface on a computer system
with which information is transferred in or out one bit at a time (contrast parallel port).
Throughout most of the history of personal computers, this was accomplished
using the RS-232 standard over simple cables connecting the computer to
a device such as a terminal or modem.
Mice, keyboards, and other devices were also often
connected this way.
While RS-232 originally specified a 25-pin D-type connector, these were
large and awkward, and most of the pins were unused (after all, since data
is sent one bit at a time, only one wire is needed for data in each
direction plus a few control signals), so it was common to use other
connectors for these ports (in particular the 9-pin version used by the
original IBM PC).
In Europe, the related RS-422 standard was popular, and often used
German DIN connectors.
In very recent years, more advanced electronics has made possible more
reliable and higher-speed serial communications, so RS-232 is being supplanted
by newer standards such as USB and Firewire.
These make it possible to connect devices that would not have been
feasible over slower serial connections, such as storage devices and
sound and video devices.
In Linux, the serial port devices are usually called /dev/ttyS* where * is a number starting with 0.
