Abstract

Abstract A retry mechanism facilitates release of a communications path by a device which is either unable to respond to a requested operation or which is unable to do so within a reasonable length of time. The mechanism is easily implemented and has a wide variety of applications, including use in operations requiring a number of transactions on «interlocked» type communications paths to accomplish a given function. It is also particularly useful in facilitating interconnection of cummunica- tions paths controlled from independent control sources.

Total Claims: 2
Claim 1
Independent Claim 76 words
In a device which communicates with other devices over a common communications path in a digital computer system, the improvement comprising, in each device: A. means for communicating to said device over a first plurality of signal lines in said path a transaction requesting a selected response, B . means for instructing the transaction initiating device over a second set of lines in said path bus to-terminate the transaction and repeat it at a subsequent time.
