Mnemonic
RTS1 EIA-232-D Request to Send (serial port 1). Input from modem
to terminal when the modem is required to transmit a message.
With RTS1 off, the modem carrier remains off. When RTS1 is
turned on, the modem immediately turns on the carrier.
CTS1 EIA-232-D Clear to Send (serial port 1). Output from modem
to terminal to indicate that message transmission can begin.
When a modem is used, CTS1 follows the off-to-on transition of
RTS1 after a time delay.
TXD2 EIA-232-D Transmit Data (serial port 2). Data to be
transmitted; input to modem from terminal.
RXD2 EIA-232-D Receive Data (serial port 2). Data which is
demodulated from the receive line; output from modem to
terminal.
RTS2 EIA-232-D Request to Send (serial port 2). Input from modem
to terminal when the modem is required to transmit a message.
With RTS2 off, the modem carrier remains off. When RTS2 is
turned on, the modem immediately turns on the carrier.
CTS2 EIA-232-D Clear to Send (serial port 2). Output from modem
to terminal to indicate that message transmission can begin.
When a modem is used, CTS2 follows the off-to-on transition of
RTS2 after a time delay.
DTR2 EIA-232-D Data Terminal Ready (serial port 2). Input to
modem from terminal; indicates that the terminal is ready to
send or receive data.
DCD2 EIA-232-D Data Carrier Detect (serial port 2). Output from
modem to terminal to indicate that a valid carrier is being
