Yes. (I currently rely on this ability for some of my workflow as
I use the EDT keypad layout when editing in emacs.)
You need a decent terminal emulator which supports DEC keyboard
escape sequences correctly and can go into application keypad mode.
For me, xterm with a script[*] I picked up from comp.os.vms a decade
or so qualifies as does the pterm component of PuTTY.
In both cases, I am running the keyboard permanently in application
keypad mode, rather than messing around with going in and out of
application keypad mode when entering/exiting emacs. This may not be
suitable for you and you may choose to do the switching yourself
as required.
You then have two choices:
1) You can look at a version of tpu-edt.el from early emacs 22.x or
before which shows how to turn the incoming escape sequences into
something can be processed within your emacs code.
2) Sometime after this, tpu-edt.el was rewritten to drop the direct
processing of escape sequences (and utterly breaking character cell
support in the process; I've only just discovered this after switching
to a newer LTS version of Linux and I've just notified the tpu-edt.el
author).
However, even in this broken version, when TERM is set to vt200, the
keypad keys other than PF1-PF4 still work when in application keypad
mode, so this might be enough for you. If so, have a look at a current
version of tpu-edt.el and you might be able to see something which you
can use; this would appear to be an easier approach than directly
processing escape sequences in your case.
Simon.
[*] There's a script on http://invisible-island.net/xterm/xterm.faq.html
which might help you get started if you choose this approach; you want
one which maps Num Lock to PF1; these specific scripts I have not tested
however.
