Signal Name and Description
DATA STROBE (Printer) - an active low output pulse
used to clock data from the system to the printer.
DATA (bit 0) (Printer)
DATA (bit 2) (Printer)
DATA (bit 4) (Printer)
DATA (bit 6) (Printer)
GROUND
PAPER EMPTY (Printer) - out of paper.
INPUT PRIME (Printer) - an output signal that clears
the printer buffer and initializes the logic.
GROUND
CLEAR TO SEND (Serial Port 3) - CTS is a function
supplied to the terminal by the modem, and indicates
that it is permissible to begin transmission of a message.
When using a modem, CTS follows the off-to-on
transition of RTS after a time delay.
DATA CARRIER DETECT (Serial Port 3) - sent by the
modem to the terminal to indicate that a valid carrier is
being received.
TRANSMIT DATA (Serial Port 1) - data to be
transmitted is furnished on this line to the modem from
the terminal.
RECEIVE DATA (Serial Port 1) - data that is
demodulated from the receive line is presented to the
terminal by the modem.
REQUEST TO SEND (Serial Port 1) - RTS is supplied by
the terminal to the modem when it is required to
transmit a message. With RTS off, the modem carrier
remains off. When RTS is turned on, the modem
immediately turns on the carrier.
