ABSTRACT:
A computing system has a wireless interface, for example an infrared interface. The infrared interface is used to directly transmit configuration information to and/or receive configuration from a configuration storage device without going through the standard I/O interfaces of the computing system. This is done by connecting the infrared interface directly to the configuration storage device. Alternately, the infrared interface is used to allow direct connection to a memory bus without using an I/O bus. This allows the computing system to send out diagnostic information without using the I/O bus. The infrared interface can be full duplex allowing requests for diagnostic information to be made by a handheld computing system such as a handheld computer or a calculator. The infrared interface may also be used to download data and programming code to a handheld computing system and for receiving data from the handheld computing system.
