To connect a serial device
The expansion base includes a standard 9-pin serial port that you can use to connect
devices such as external modems and fax modems. If needed, you can set the serial port’s
address in the BIOS Setup utility.
• Connect the device’s serial cable to the expansion base’s serial port.
To connect an infrared device
If your computer includes an infrared port, you can use it to provide serial
communication between the computer and other infrared devices, such as printers or
other computers.
By default, the infrared port is not enabled, so you must enable it before you can use it.
1. Enable the infrared port in the BIOS Setup utility—see “To run the BIOS Setup
utility“ on page 189.
2. Windows 98 only: click Start, Run, and type c:\hp\drivers\fir\quikbeam\setup.exe to
install the QuickBeam software. For more information, see the Readme file in the
same directory.
Using the infrared port
• Make sure the infrared ports of your computer and the other device lie in as straight a
line as possible. The two ports should be no more than 1 meter apart, with no
obstructions between them.
• To check the status of communications, open Infrared (Windows 98) or Wireless Link
(Windows 2000 or XP) in Control Panel.
Disabling the infrared port
You should generally disable infrared communication when you aren’t using it.
1. Close any applications that are using infrared, and any folders on an infrared link.
2. Click Start, Settings, Control Panel (Windows 98 or 2000) or Start, Control Panel,
Printers and Other Hardware (Windows XP).
