Infrared Port

The computer’s infrared (IR) port is compatible with IrDA 1.1 (Fast IR) and 1.0 (Slow IR) standards. An infrared

port lets you transfer files from your computer to another infrared-compatible device without using cable

connections. An infrared data stream is transmitted through a lens in the computer up to a distance of 1 m (3.3 ft).

This light is received by a compatible computer, printer, mouse, or remote control.

The default address of the infrared port is COM3. To avoid resource conflicts with other devices, remap the

address of the infrared port.

When the computer is being used with the C/Port APR or C/Dock Expansion Station, the infrared port on the

computer is automatically disabled.

Point the computer’s infrared port directly at the compatible device’s infrared port. Infrared devices transmit data
