Abstract:
A device () that includes a communications port (), a first processor (), at least a second processor (), and a multiplexer (). The multiplexer can selectively communicatively link the communications port to the first processor or the second processor. The multiplexer can include at least one switch () and a switch controller () that controls operation of the switch. The switch controller can be responsive to at least one control signal () generated by the first processor. The first processor can generate the control signal in response to a command received from an external device () connected to the communications port. The command can be an attention command or a test software command. The switch controller also can be responsive to at least one control signal generated by the second processor.
