2.5.3 Installing an External Serial Port Device
The notebook contains an external RS-232 serial port with a 9-pin, male DB-9 connector
as shown in Figure 2-6 (25-pin cables require the use of an adapter for use with the 9-
pin port). The serial ports are used to interconnect such devices as:
♦External Modem
♦Serial Mouse
♦Serial Printer
♦Any device that uses an RS-232 interface
Caution: Never connect a parallel device to a serial port or a serial device
to a parallel port or video port; this may cause damage to the notebook
and/or external device. If you are uncertain of what type connector the
external device has, refer to the technical manual for the external device.
