Serial Port
The integrated serial port uses 9-pin D-subminiature connector on the back panel. This port supports devices such as external modems, printers, plotters, and
mice that require serial data transmission (the transmission of data one bit at a time over one line).
Most software uses the term COM (for communications) plus a number to designate a serial port. The default designation for your system's integrated serial
port is COM1.
Serial Port Connector
Figure B -2 illustrates the pin numbers for the serial port connector and Table B -1 defines the pin assignments and interface signals for the serial port
connector.
