1.7.3 Serial and Parallel Interface Ports
This system is equipped with two serial ports and one parallel port. Both types of
interface ports will be explained in this chapter.
1.7.3.1 The Serial Interface: JCOM1/ JCOM2
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, where it 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 port on this system has two 9-pin connectors. Some older computer
systems and peripherals used to be equipped with only one 25-pin connector. If 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.
