Infrared - HP Notebook Reference Manual

Infrared

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 signals are sent through an invisible beam of infrared
light and must have an unobstructed line of sight. Infrared
performance may vary with the performance of infrared
peripherals, the distance and angle between infrared devices, and
the applications being used.
