        N/A               20ma current loop                 Y     N

        *  The 25th data line command is implemented differently on
           the WY185 in that the current page format (1x or 2x) will
           also be taken into account and screen data is lost when
           command is executed. (i.e from 25th data line OFF to ON and
           vice versa)
