bind function key difference between terminal and Xterm

bind function key difference between terminal and Xterm

[Xend]

#grep enlarge-window ~/.emacs
  (global-set-key (kbd "C-<up>") 'enlarge-window)
#runlevel
 3 5
# emacs
 >>enter
     M-x split-window
     M-x other-window
     <up> ;; the lastest window is enlarged.
      ctrl + <up> ;; it can't work but display ';5A' in window

but when i run Xterm and then execute GNU/Xemacs, ctrl + <up> can
enlarge window. why is it? how can i set to enlarge window with "ctrl
+ <up>" in terminal??

By re-writing its emulation or the terminal's firmware! C-up is an  
event in a windowing system. A terminal or its emulation has no idea  
of this concept.

Simple proof: type in *scratch* buffer C-q <up> and also C-q C-<up>.  
They're the same ANSI Esc sequence, aren't they?

C-up is an event in a windowing system. but it's not an event in
Terminal. why EMACS can't catch it.

GNU Emacs, when launched without windowing, is a client of its host,  
the terminal or terminal emulation. What Emacs receives are not  
events – the terminal emulation, when running in a windowing system,  
does receive them – but ANSI Esc sequences, by which the cursor can  
change its shape or gets positioned or is moved or text elements are  
emphasised etc. Teach your terminal emulation to send different codes  
for <up> and C-<up> keyboard input, then GNU Emacs will be able to  
distinguish between them.
