*'''Pin 1''' - Data Carrier Detect (DCD) indicates that the carrier for the transmit data is ON.

*'''Pin 2''' - The receive pin (RXD) carries data from the serial device to the computer.
 +
*'''Pin 3''' - The transmit pin (TxD) carries data from the computer to the serial device.
 +
*'''Pin 4''' - Data Terminal Ready (DTR) indicates to the modem that the computer is ready to transmit.
 +
*'''Pin 5''' - Ground.
 +
*'''Pin 6''' - Data Set Ready (DSR) is similar to DTR. It indicates that the Dataset is ON.
 +
*'''Pin 7''' - The RTS pin requests clearance to send data to a modem.
 +
*'''Pin 8''' - The serial device uses the Clear to Send (CTS) pin to acknowledge the RTS signal of the computer. In most situations, RTS and CTS are constantly ON throughout the communication session.
 +
*'''Pin 9''' - An auto answer modem uses the Ring Indicator (RI) to signal receipt of a telephone ring signal.
