Does doing WRITELN to screen enable hardware interrupts?

Data aquisition software I've written uses hardware interrupts
(typically int 5). There's times when I wish to disable it by turning
off interrupts using

asm cli; end;

But it seems as though they get turned back on if I write something to
the screen using "writeln". Could this be true, and why, and any way
to avoid it?

Make your own writeln routine which draws directly to screen
memory.
