Abstract

Disclosed is an intelligent portable computer terminal which eliminates hardware function of data tone discrimination (bit 0 tone versus bit 1 tone) by incorporating this function into system microprocessor operational code, thereby freeing the hardware system of this additional complexity. The implementation illustrated employs the same system microprocessor as the central computing and control element, the timing element, and the frequency discrimination element.
