Indeed. I was thinking this as a preliminary patch. I am not familiar with
the code base and probably some things might be done better too (like
the clear command below).

These changes were because the \004 command on init didn't disable
the cursor for me thus I included it on every screen cleanup. Also the 014
command although seemed to work, it is something else on my
CZ632 (014=backlight control). Thus I changed it with 012 which is the
form feed.
