With keypad mode disabled numlock on will give you configuration A, and numlock
off will give you configuration B. With keypad mode enabled you'll get
configuration C.

Terminals that support keypad mode
Linux Console, PuTTY, Eterm, aterm.

Terminals that do not support keypad mode

Peculiar Terminals

RXVT requires turning off numlock to enable configuration C.

Xterm may require disabling Alt/NumLock Modifiers (num-lock) in the ctrl-left
click menu. Or edit ~/.Xresources and add XTerm*VT100.numLock:false

Mac OS X Terminal requires enabling 'strict vt100 keypad behavior' in
Terminal -> Window Settings -> Emulation.
