Did you try to look in the DJGPP FAQ list (available as v2/faq210b.zip 
from the same place you get DJGPP)?  In section 12.5 (which deals with 
debugging graphics programs) it mentions a program named MSHELL that will 
redirect any program's I/O to the mono display at the BIOS level (so you 
could just use `printf' and it miracolously ends up on the mono display).

You can also use the `_mono_printf' function from the DJGPP library.  Look
it up in the libc reference.  It works like `printf', but the output goes 
to the mono display.
