Some video cards will re-route fprintf() output to the screen even when
in graphics mode, some don't.

ex: Diamond Stealth's do
    Number Nine's don't

(both of these use S3 chipsets so that must be a bios feature.)

A good clue to tell whether or not you're still in GFX mode, is the size
and color of the font. Or you can just type Mode CO80 like he said, and
if the screen flickers or resizes, etc., then you know.

I currently don't have the latest version of Allegro installed, or I'd
test his code and possibly confirm his problem.

Good luck,
