Passthru Feature for Facsimile Machine

       Disclosed is a means for controlling and enhancing the
operation of a facsimile machine with an attached personal computer.

      Some prior art facsimile machines provide an external interface
to a host computer to allow the computer to use the facsimile machine
as a scanner or printer, and to allow facsimile communications to be
routed to/from memory files rather than paper.  However, these
machines do not provide a way for the host computer to augment the
communications protocol or image data format over what exists in a
standalone version of the machine.

      This disclosure allows the host computer to extend the basic
communications ability of the facsimile machine by replacing the
protocol embedded in the facsimile machine with one supplied by the
computer.  Similarly, the computer can supply the image data in any
format, not limited to the format known to the standalone machine.
The job of directing facsimile communications is passed from the
computer, through the facsimile machine control logic, to the
facsimile modem hardware.

      With the passthru feature, the standalone facsimile can be a
very simple, low-cost machine with only the basic facsimile
requirements implemented.  When the user requires more function, this
low-cost machine is attached to a host computer running the passthru
software program.  The passthru software can provide additional
standard capability (e.g., two-dimensional co...
