The G3 utility may be used to analyze the contents of a G3 file
    in a G3_TO_FAX channel queue directory. In addition, the G3
    utility is capable of converting a G3 file to a DDIF file which
    may then be viewed with the HP CDA Viewer. If you merely want to
    view header and delivery information in a G3 file, then use the
    /NOCDA qualifier. This will disable the time-consuming output of
    a DDIF file containing the bitmap images stored in the G3 file.

    Information about each of the To: recipients in a G3 file may be
    edited using the edit mode invoked with the /EDIT qualifier. This
    allows incorrect FAX telephone numbers to be edited, delivery to
    specific recipients to be cancelled, etc.

                                   NOTE

       The G3 utility is part of the PMDF-FAX software product. It
       is not part of the base PMDF distribution.
