A technique is described whereby a computer software package operates in conjunction with interconnecting interface software, such as used in computer network applications. It is an improvement over the traditional "in-line" code approach used to monitor interconnecting signals, but operates in a background mode so as to distinguish valid signal transitions from unwanted signal transitions. It then transforms the physical communication line transitions into stable information. It is not confined to communication line monitoring, but can be implemented in single or multiple lines interconnecting computers and/or terminals, in that software systems which require reliable information from a hardware interface can utilize this concept.
