I should point out that this is entirely non-trivial.  In fact, I don't think
it can be done in the (completely) general case.

Problem is that characters come in one at a time to INT 10, fn 9, sans
any carriage control or screen handling (all of which is done via other
INT 10 functions)  It would be a task to reconstruct the original screen
display.
