Linking to an Infrared Device

The notebook is IrDA-compliant and can communicate
with another infrared-equipped device that is also
IrDA-compliant. The IrDA connection speed standard is
4 megabits per second (Mbps).
The infrared port supports low-speed connections up to
115 kilobits per second (Kbps) as well as high-speed connections
up to 4 Mbps.
Infrared performance may vary with the performance of infrared
peripherals, the distance and angle between infrared devices, and
the applications used.
Infrared signals are sent through an invisible beam of infrared
light and require an unobstructed line of sight.
