Looking over old email, I find I may have made a mistake.  A few weeks ago I
discovered that the generic driver supports the Hopf 6021 - it's subtype 12.
Accordingly, forgetting that I had received this request, I deleted the
dedicated Hopf 6021 driver.

The dedicated 6021 driver can be restored, but I would prefer not to do it
if generic subtype 12 works.  Parse drivers are smaller and better factored
than the standalone ones - the right direction is to move code into the
generic driver, not out.

Martin, would you please test that generic mode 12 on a 6021?
