  • Patent number: 5453847
    Abstract: A system of transmitting computer display information as facsimile pels through conventional facsimile machines. The system comprises a conversion means for scaling each dot of display into facsimile pels using a scaling factor which is used to scale both the width and height of each dot of display. Each dot of display is output as some whole number of facsimile pels. Given that many facsimile machines have no memory, the facsimile pels are temporarily stored as encoded data and output in a steady stream of data bits to the facsimile machine. This frees up the limited memory of the MCU of the pocket size computer.
