This article describes a technique which insures that users of serial facilities in a distributed data processing system (DDP) system are properly sequenced. In a DDP system, such as the one disclosed in [*], where serial use facilities, such as system printers, have been attached as stand- alone nodes in an insertion ring, a set of orders is defined to allow the shared use of these resources without requiring the invocation of a central manager located in some processor node. A Request Session order is transmitted to the desired facility with a Session Granted response being required before any work will be accepted. A Session Busy response will be an indication that the requestor has been queued.
