  My Hercules Graphics Card Plus requires a special screen
blanking utility, which Hercules thoughtfully supplies.  Un-
fortunately, this routine blanks the screen after five minutes
of no keyboard activity.  It does not check for mouse activity
and the screen frequently goes blank in the middle of mouse-
based applications.  I can restore it by touching alt or ctrl
or shift, but I'd prefer not to.

  Hercules sent me the assembler source code for the screen
blanker and I would like to modify it to check for mouse
activity.  If anyone out there has a mouse manual, could you
please send me email explaining how to do this?  I understand
that the mouse is called with 33h, but I have no idea what
goes in which register.

  Thanks for any suggestions.  I'll post a summary in a couple
of weeks.
