You can check this with emacs -Q.

I wouldn't call this "xterm mode" as just about any
terminal emulator (urxvt, Gnome terminal, etc.) should
be able to do this.

But actually the Emacs help mentions xterm:

    -nw, --no-window-system
            Tell Emacs not to create a graphical  frame.   If  you  use
            this  switch  when  invoking Emacs from an xterm(1) window,
            display is done in that window.

Here is a tutorial if you want to rebind it:

    http://user.it.uu.se/~embe8573/tty-emacs-keys.txt

use, e.g.:

    (define-key input-decode-map [?\u0114] [C-/])

The Linux VTs are not the same as X. xterm may appear
closer to the Linux VTs but it is not: it *is*
"x"term, aye?

PS. I have `undo' M-0 - very fast, close, and
ergonomic if I may... DS.
