If you use a notebook computer, you most likely have an infrared port. Most notebook computers come with an infrared port built in; look at the back of your notebook and you should be able to find it. The port is usually a dark red color. Figure 7-1 shows the infrared port at the back of an HP notebook.
It is rare to find an infrared port on a desktop computer. Most desktop manufacturers have not incorporated infrared functionality into their design, mainly because of the lack of demand for it. However, you can add infrared functionality into your desktop by purchasing a relatively cheap (under $50) infrared adapter. Figure 7-2 shows a USB infrared adapter. To use it, simply plug the adapter into the USB port and Windows XP will automatically recognize and install the driver for the device.
