Wireless host with improved roustness and boot capabilities
A wireless host is used with a computer having a BIOS, an operating system, a serial bus interface coupled with the BIOS, the wireless host operating under a protocol that functions only in the presence of a corresponding wireless communications driver in the operating system, and the BIOS characterized in that human interface device information received via the serial bus interface is made available to the operating system by means other than the wireless communications driver. Human interface device information is received via the wireless host. Depending on a predetermined condition, the human interface device information is passed to a wireless communications driver in the operating system, or is passed to the serial bus interface and is made available to the operating system by means other than the wireless communications driver. The predetermined condition may be the absence of the wireless communications driver, or for example may be the determination that the human interface device information is an escape sequence. In this way, user communications to the computer can be robust even in the event of operating system or software failure.
