I took a good stare at the VT220 Programmers Reference. It looks like
'application mode' isn't that special. It really looks very similar to
the way the keypad is handled on the PC - in one mode you get the
numbers on the keypad, and in the other mode you get an ESC string to
indicate special keys.
