RETRY MECHANISM FOR RELEASING CONTROL OF A COMMUNICATIONS PATH IN A DIGITAL COMPUTER SYSTEM

摘要

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 communications paths controlled from independent control sources.
