Unfortunately, while most terminals claim vt100 compatibility, they
lot of them lack the so-called "application cursor mode". This is
the only reasonable portable to use the keypad arrows, so #keypad won't
work on those terminals.
Terminals I checked:
* Linux console:
works just fine
* PuTTY:
works just fine
* aterm:
works just fine
* rxvt:
newer versions work fine, older ones have a bug that causes the
down arrow to be misreported as the diagonal up-left one. This
bug is hard-coded in rxvt -- so the only option that doesn't
involve patching the source is upgrading to a newer version.
* wterm:
it's based on old rxvt code, and I'm not aware of a fixed version.
Of course, you can just get the sources and apply this patch:

* Eterm:

* gnome-terminal:
in recent versions, the keypad is available in gnome-terminal's vt220
mode. Thus, KBtin will attempt to switch to it. Too bad, a few of
the key codes are wrong -- KpadDivide is reported as KpadMinus, and
KpadMinus as ESCOm.
* konsole:
doesn't work, and I'm not aware of a workaround
* xterm:
in many cases, it can be switched to an appropriate mode, with same
problems as with gnome-terminal. Otherwise, it requires some tinkering
with xmodmap. It seems that feeding the following to xmodmap will make
#keypad work (making the NumLock key stuck as a side effect, though).
keycode 79 = KP_7
keycode 80 = KP_8
keycode 81 = KP_9
keycode 83 = KP_4
keycode 84 = KP_5
keycode 85 = KP_6
keycode 87 = KP_1
keycode 88 = KP_2
keycode 89 = KP_3
keycode 90 = KP_0
keycode 91 = KP_Decimal
(thanks Elariel for this solution!)
