Setting Up an Infrared Device

Many of the latest notebook computers come with a built-in infrared (IR) port. This port acts like both a serial port and a parallel port, and you can use it to transfer files and send print jobs. (For sending print jobs, you need a printer—such as the HP LaserJet 5MP—with an IR port. You can find more on this topic in Chapter 21, “Prescriptions for Perfect Printing.”) You can also purchase infrared devices that attach to a serial port.
