摘要:
Disclosed is a Software Sanity Monitor for automatically detecting and remedying software lock-up conditions without user intervention. Users often refer to these conditions as "hangs" or "forever loops". Although the Software Sanity Monitor uses the operating software's information, it is designed to execute independent of the operating system software; thereby, eliminating reliance on a "sane" operating system. If a "hang" condition is detected, the Software Sanity Monitor will automatically restart the system after logging the failure and, optionally, notify the user or host system.

A method of reading a plurality of bar codes during a scanning motion across a bar code scanner, which enhances scanner operation, is disclosed. The method includes the steps of obtaining data from a detector in the bar code scanner, determining position information associated with the data, distinguishing data associated with each bar code using the position information, and assembling the bar codes from the data.

To improve the throughput of bridges in a multiple ring token ring network, External Copy Hardware (ECH) (120) is provided for each source routing bridge (118) to determine when a frame on a given ring (111) is to be copied as a candidate for forwarding to another ring (222) by a given bridge (118). Each frame may contain a Routing Information Field (RIF), which the ECH (120) searches for Segment Numbers in the RIF that are compared with host processor developed Primary Segment Numbers (each representing a primary ring number and a bridge number) and Secondary Segment Numbers (each representing an alternate ring number and a bridge number). The ECH (120) uses the results of the comparisons along with a look-up table and a Routing Control Word (also present in the RIF) to determine if the frame under consideration is to be copied by a Protocol Handler (which interfaces with the ECH) and forwarded by the corresponding bridge (118) to another ring. During the process of making a copy or non-copy decision, the frames are scanned unidirectionally, and the decision is made "on the fly", thereby increasing operation speed.
