Abstract
A centralized control unit for use in a multisystem data processing configuration to provide dynamic access to shared and non-shared peripheral subsystems is disclosed. This unit, known herein as a subsystem access unit (SAU) is able to remotely control one or more system's accessibility to peripheral subsystem's from a central location. It is able to provide this control with the capability of either allowing a peripheral subsystem to be concurrently accessed by more than one system or forcibly ensuring that the peripheral subsystem is exclusively accessible by only a single system.
