This must be a FAQ, I know...

How can you change the screen into a different(_text_) video mode with 
djgpp? Basically, I'd like to switch the screen height to 28 lines 
(assuming I'm on a VGA) and stay there. I'd fit more information on the 
screen that way and the 28-line font is also nicer than the 25-line.

This is done in pdcurses, for example, by calling BIOS interrupt 0x11 
with AL=0x11 and BL=0, then interrupt 0x12 with AL=2 and BL=0x30. But 
pdcurses does this just internally when `restoring' the screen, it 
doesn't provide any means to the outside, it seems. Is my only option 
calling int86() to death?
