There are only 240 horizontal pixels to work with -- you can't show a
character with only two pixels (the third would be the space between).
If the DOS they use is pretty much standard, you won't find a built in mode
that will give you more than 40 chars. You would have to 1) write your own
int 10h subservice (steal the interrupt), AND 2) create a special font (you
MIGHT get 60 chars max -- very unreadable) and manage the screen memory
yourself (enjoy!)
