IrDA infrared port
The IrDA-compatible infrared port (Figure 2-4) enables wireless serial data
transfer between any peripheral device or computer equipped with the IrDA
interface. You can select infrared port as FIR or SIR from the BIOS setup. The
infrared port can only be used when UART2 mode is set to FIR or SIR in the
Integrated Peripherals setup in the BIOS setup.
In order for reliable infrared data transfer to occur, the eBuddy should be
placed within three feet of the other infrared device. In addition, the two infra-
red ports (on the eBuddy and the other device) must be aligned within a range
of 30° horizontally and 15° vertically.
The following instructions explain how to set up the infrared port for operation
in Windows 98.
