Using the Infrared Port

Communicating with Infrared

■If the computer is running Windows 98 or a preinstalled Windows 95 operating system, the computer is IrDA-compliant (4Mbps standard) and can communicate with any another infrared-equipped device that is also IrDA-compliant.

■Infrared communication is supported by Windows 95 and Windows 98. To operate infrared on computers running Windows NT 4.0, you will need to purchase optional third-party software.

NOTE: The infrared port supports both low speed connections up to

115 kilobits per second (Kbps) and high speed connections up to 4 megabits per second (Mbps). Infrared performance may vary depending on performance of infrared peripherals, distance between infrared devices, and applications used.
