I'm not sure how textcolor sets the video attribute, whether it's set in
a variable in the conio library or if it actually changes the screen attributes
at the same time. Either way, the ANSI driver is oblivious to this change (where
printf's out put is going) the correct sequence would be:
#include <conio.h>
main()
{
	textcolor(RED);
	cprintf("This oughta work\r\n"); (the \r is needed since this is RAW IO)
}

Hope this helps....
