ABSTRACT:
Apparatus for comparing a stream of data characters with a predetermined string of test characters has an input device for receiving the stream of data characters and a main processor for generating the predetermined string of test characters. A hardware register receives the predetermined string of test characters from the main processor, and a comparator device compares the stream of data characters with the contents of the register device and generates a response in the event that a portion of the stream is identical to the string of test characters generated by the main processor. A second processor receives the response and sends a report to the main processor.
