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.
