Looking at the rare chip documents I got, I often saw internal control
values on 3 bytes (16 million values). Could anybody see the difference
between values v and (v+1)?
So, often, even when the internal controls are stored in only one byte,
the ms-win drivers propose only ranges as 0..30 or 0..100.
