Abstract
A method for detecting dropouts in digital data transferred over a bus from a digital data source to a computer system. Each address in the computer system buffer memory is initialized to a selected code value known not to exist in the data to be transferred. After sequential transfer of data to the buffer memory, the presence of the selected code value in the buffer memory indicates that a dropout occured.
