ABSTRACT:
A system for effecting communications between a computing device and a plurality of peripheral devices which comprises a bus controller for controlling the communications, a plurality of feedback generator circuits for providing operational status information, each of the plurality of peripheral devices having an associated one of the plurality of feedback generator circuits. The system further comprises a bus for conveying signals between the bus controller and the plurality of peripheral devices. In the preferred embodiment, each of the plurality of peripheral devices has a respective address and each of the plurality of feedback generator circuits contains the operational status information for its respective peripheral device. The bus controller interrogates the plurality of peripheral devices, each of which causes its respective feedback generator circuit to respond to such interrogation by communicating its respective operational status information to the bus controller when a respective of the peripheral devices indicates that such information is to be passed.
