Abstract

This article describes an arrangement for use in a multi-adapter programmed control unit which inhibits adapter bidding for a program interrupt level after communication between the adapter and the program is lost due to either a hardware or software failure, thus permitting other adapters to remain operational in the event that the failure is unique to one or more of the adapters.
