Serial and Parallel Interface Ports
This system comes equipped with two serial ports and one parallel port. Both types
of interface ports will be explained in this chapter.
1.7.4.1 The Serial Interface: JCOM1
The serial interface port is sometimes referred 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 with another computer system. If you wish to transfer the contents
of your hard disk to another system it can be accomplished by using each machine’s
serial port.
The serial ports on this system have two 9-pin connectors. Some older computer
systems and peripherals used to be equipped with only one 25-pin connector.
Should you need to connect your 9-pin serial port to an older 25-pin serial port, you
can purchase a 9-to-25 pin adapter.
