SERIAL
SHARING DEVICES |
All IBM PC and compatible computers
are equipped with serial ports for communicating with external
devices. A serial port sends and receives data one bit at
a time over one wire. While it takes eight times as long to
transfer each byte of data this way in comparison to a parallel
port, only a few wires are required. Usually, the serial port
is "Full-duplex", meaning it can send and receive
data simultaneously. This is possible when there are separate
lines; one for transmitting and one for receiving. Some devices
support only one way communication and only have two wires
- one for transmitting and one for the signal ground.
Two terms that are important to be familiar with are DTE
& DCE. DTE stands for Data Terminal Equipment, and
DCE stands for Data Communications Equipment. These terms
are used to indicate the pin-out for the connectors on a device
and the direction of the signals on the pins. Your computer
is a DTE device, while most other devices are usually DCE
devices. DTE & DCE DETERMINATION GUIDE DTE DEVICES Terminals
(Gender: Male) DCE DEVICES Modems, CSU/DSU, Multiplexers (Gender:
Female) SELECTABLE DTE OR DCE DEVICES Routers, Hubs, Switches,
Access Servers (Gender: Either) Selectable devices usually
have a jumper, switch, or software command used to select
either DTE or DCE. |
Serial connectors include the 9Pin
and the 25Pin (DB9 & DB25 both Male or Female connectors). |
