Qué (quién) es Data Terminal Ready - definición
Data Terminal Ready
CONTROL SIGNAL IN RS-232 SERIAL COMMUNICATIONS
Data terminal ready
<communications> (DTR) The wire in a full RS-232 connection
that tells the Data Communication Equipment (DCE, typically
a modem) that the Data Terminal Equipment (DTE, typically
a computer or terminal) is ready to transmit and receive
data.

Data Terminal Ready
CONTROL SIGNAL IN RS-232 SERIAL COMMUNICATIONS
Data terminal ready
Data Terminal Ready (DTR) is a control signal in RS-232 serial communications, transmitted from data terminal equipment (DTE), such as a computer, to data communications equipment (DCE), for example a modem, to indicate that the terminal is ready for communications and the modem may initiate a communications channel.
Data Terminal Equipment
COMMUNICATIONS SYSTEM EQUIPMENT
Data Terminal Equipment; Data terminating equipment; Datenendeinrichtung; DTE (telecommunication); DEE (telecommunication)
<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.
