Yes, we had the same trouble in january.  I presume you are using ttya
as a console ? (i.e. You haven't got a sun console, keyboard and mouse).

This is a documented bug, look in the CDB.  The problem is that the
TERMCAP definition cannot be set from within suninstall, its buffer for
the termcap entry is too small.  If you set the TERMCAP variable with
the correct value before running suninstall, you should have no
problems.  (This took us, sun NL, two weeks, plus a hardware engineer
for half a day at our site swapping boards, until they realised what was
happening).

I know nothing of problems with typeahead in suninstall, apart from the
stupid program reacting a bit slow.  [[ Well, it may have just been us.
Hard to tell sometimes, and "suninstall" is not something we use that
often (so it's not worth the effort of tracking down problems in it).
