Abstract: A communications adaptor comprises a receiver circuit, which can comprise a signal input configured to receive a frequency shift keyed (FSK) signal; a delay circuit in communication with the signal input and including a delayed signal output; a multiplier circuit in communication with the signal input and the delayed signal output, and the multiplier circuit can be configured to produce a serial bit steam from at least the signal input and the delayed signal output, the serial bit stream corresponds to one or more bits encoded with frequency shift keying in the FSK signal; and a signal output configured to output the serial bit stream. The communications adaptor also can comprise a transmitter circuit and a processor in communication with the receiver circuit and the transmitter circuit.

Abstract: A method and apparatus for programming a mass storage device of the type having a plurality of memory word locations. The memory word locations are organized into a plurality of addressable columns and addressable rows, each memory word location capable of storing one byte word in response to at least two programming steps. Each programming step for a selected memory word location requires a predetermined time period before a subsequent programming step can be processed by the selected memory word location. A first programming step is applied to a first memory word location. The first programming step is applied sequentially to other memory word locations while the first programming step is being processed by the first memory word location. A second programming step is applied to the first memory word location while the first programming step is being process by the other memory word locations.
