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.
