ABSTRACT:
A system is disclosed for directing orders to peripheral devices in a data processing system having duplicate central control units. In the event one of the central control units loses access to a peripheral device, and therefore cannot transmit orders to that peripheral device, the system enables an alternative route through the other central control unit to the same peripheral device.
