  I don't have my Turbo C manual handy since I'm sitting in the middle of a
UNIX lab right now, but I have a suggestion.  There is a library function
that allows you to place an arbitrarily-sized image on the screen.  You could
then write code that displays a cursor-sized block of pixels at the CP.  Sorry
that I couldn't be more specific about this function, but if you spend a few
moments looking through the manual, I think you'll find what I'm talking about.

  This might require some extra effort, since one way to do it is to display
your own bit-mapped characters.  In that way, you could control reverse video
in a straightforward manner.
