1.7.1.3 The Serial Interfaces: COM1 / COM2
The serial interface port is sometimes refered to as an
RS-232 port or an asynchronous communication port. Mice,
printers, modems and other peripheral devices can be
connected to a serial port. The serial port can also be used
to connect your computer system. If you like to transfer
the contents of your hard disk to another system, it can be
accomplished by serial port.
1.7.1.4 Parallel Interface Port
Unlike serial ports, parallel interface ports have been
standardized and should not present any difficulty interfacing
peripherals to your system. Sometimes called a Centronics
port, the parallel port is almost exclusively used with printers.
The parallel port on your system has a 25-pin, DB 25
connector.
