Anybody knows how one can turn off/on the video in HERCULES mode?  I use the
command below

      port [$03B8] := $21              { Turn off monochrome screen }
      port [$03B8] := $29              { Turn on monochrome screen }

They work in mono mode but not in graphic Hercules mode.

      Thanks.
