ABSTRACT:
An apparatus and method for unilaterally-controlled, time-insensitive recovery of disconnected data links provides for user-transparent recovery, without requiring inputs from a user or other intervention. Data and executable operations may be preserved, as re-booting is not required. Optionally, opportunity for user intervention may be provided, at a user's request. Recovery may occur automatically by use of expert knowledge applied to reported system errors from the disconnected communication link. An apparatus may rely on a logical device within an actuator or machine of mechanical, pneumatic, hydraulic, electrical or electronic character. A task to be reported to an actuator as successful or failed, may be internal to the actuator, internal to the logical device, or external to both. Data structures stored in a memory device, may implement the invention readily from within an application running on a processor in a computer. Information (data, operational steps) may be preserved at an atomic level of granularity.
