The present invention relates to a wireless interface device and more particularly to a wireless interface device for interfacing with a host computer connected in either a wired or wireless local area network. Once a connection is made between the wireless interface device and a host computer, the host computer is under the control of the wireless interface device. In order to provide a convenient way to return control back to the host computer, a hot icon is provided on the wireless interface device which, in response to a pen-down event, automatically returns the control back to the host computer.

System and method for switching control between a host computer and a

A computer system includes a flash memory device for storing BIOS code. The BIOS code is stored in an unprotected area of the flash memory. A boot block, stored in a protected area of the flash memory, is used for rebooting the computer system in the event that the flash memory device becomes corrupted. During normal operation, the BIOS code is updated using a radio link. If the BIOS is corrupted while being updated, a recovery routine stored in the boot block is executed. The recovery routine permits the corrupted BIOS to be reprogrammed using a serial interface instead of the radio link.
