Windows XP supports the IrDA protocols, providing connectivity to the Internet and to other networks. Using Windows XP support for infrared communication, you can connect to the Internet using a dial-up infrared modem or connect to another computer through point-to-point connection. You can also connect to the Internet through a computer and a network access point.
