Data Terminal Equipment
<communications, hardware> (DTE) A device which acts as the source and/or
destination of data and which controls the communication channel. DTE includes
terminals, computers, protocol converters, and multiplexors.
DTE is usually connected via an EIA-232 serial line to Data Communication
Equipment (DCE), typically a modem. It is necessary to distinguish these two
types of device because their connectors must be wired differently if a
"straight-through" cable (pin 1 to pin 1, pin 2 to pin 2 etc.) is to be used.
DTE should have a male connector and should transmit on pin three and receive on
pin two. It is a curious fact that many modems are actually "DTE" according to
the original standard.
