Allows you to avoid resource conflicts by
remapping the address of the infrared ports or
disabling the port. The COM1, COM2, COM3, and
COM4 settings allow you to take advantage of the
computer's Fast IR support.
Settings for this option are:
Disabled — Disables the infrared data port and
makes the direct memory access (DMA), interrupt
request (IRQ), and I/O resources available for
another serial device to use
COM1 — Maps the infrared data port to COM1
COM2 — Maps the infrared data port to COM2
COM3 (the default) — Maps the infrared data port
to COM3
COM4 — Maps the infrared data port to COM4
For a change in the Infrared Data Port option to
take effect, you must reboot your computer.
If Infrared Data Port is set to any function other
than Disabled, specify the Infrared Mode by
selecting one of the following functions:
Fast IR — Use Fast IR if the infrared device
supports the Fast IR specification.
Slow IR — Use Slow IR if the infrared device
does not support the Fast IR specification.
