  May not be your problem, but I have some surplus LCDs that
wouldn't work at all, then magically started working when I
switched to timing only, no busy check.  I first thought it
was my code, or that I'd blown up the flags trying to get
them to work.
  I later ran across some data sheets though that indicated
that the busy flag was not implemented, don't remember which
manufacturer they were.  But apparently some low end
manufacturer(s) either saved $.002 somehow by not putting in
read back on this register, or more likely made some bugged
parts but still felt like making some money that year, and
changed the data sheets to reflect the non-feature..  So if
you can't get them to work reliably in some way that makes
sense, whether it's reading every enable or every other
enable, it's also a possibility that it may simply not be
reliable.  And I vaguely recalled having had a MPJA catalog
(or someone with similar layout) that listed a LCD with NO
BUSY FLAG or some such in the description, so they are out
there.  Too bad it took a few days worth of work before I
remembered that bit of info..
