I used xterm-200 that I compiled. 

Hmmm, it seems that xterm X.Org 6.7.0(192) (that comes with Fedora
Core 3) uses different sequences for {C-,S-,C-S-}-f[1234]
Recompiling xterm-200 with the flags the FC3 uses, I get the same
strings as the FC3 xterm.

These are the new bindings: 

  (define-key map "\eOP" [f1])
  (define-key map "\eOQ" [f2])
  (define-key map "\eOR" [f3])
  (define-key map "\eOS" [f4])

  (define-key map "\eO2P" [S-f1])
  (define-key map "\eO2Q" [S-f2])
  (define-key map "\eO2R" [S-f3])
  (define-key map "\eO2S" [S-f4])

  (define-key map "\eO5P" [C-f1])
  (define-key map "\eO5Q" [C-f2])
  (define-key map "\eO5R" [C-f3])
  (define-key map "\eO5S" [C-f4])

  (define-key map "\eO6P" [S-C-f1])
  (define-key map "\eO6Q" [S-C-f2])
  (define-key map "\eO6R" [S-C-f3])
  (define-key map "\eO6S" [S-C-f4])

  (define-key map "\eO6P" [A-f1])
  (define-key map "\eO6Q" [A-f2])
  (define-key map "\eO6R" [A-f3])
  (define-key map "\eO6S" [A-f4])

Indeed, proprietary unixes use all kind of weird sequences for
these keys. 

But it seems that X.org is now what most people seem to be converging
to. So supporting these bindings should be helpful for a lot of users.
