Try setting up a filter process (via set-process-filter) that
interprets the output of the subprocess and writes it into the buffer
just like a terminal writes the output to its screen.  Then the
process's output will have appropriate screen handling.  Make sure you
get the subprocess's termcap set right, particularly screen size.

Nothing simpler will work, because the ^L command to Emacs causes it
to redraw the screen, so Emacs has to know what the virtual screen of
the subprocess contains.
