The problem is that ESC-[ is bound to the function backwards-paragraph
already, so it can't be the beginning of a longer sequence at the same
time.  You have to say:

  (global-unset-key "\e[")

before the global-set-key.  If you use sunwindows, I recommend that
you use emacstool instead; it encodes the function keys differently
and compatibly.  If this isn't installed at your site, it should be
the file $EMACS/etc/emasctool.  (Actually, I recommend you obtain and
use the window system named X in preference to any of this).

Otherwise, look at the file $EMACS/lisp/term/sun.el; here's the relevant
bit:

  (defvar sun-esc-bracket nil
    "*If non-nil, rebind ESC [ as prefix for Sun function keys.")

Basically, this means that, if you say:

  (setq sun-esc-bracket t)

in your .emacs file, the function keys on the Sun will all be enabled
for you (modulo .ttyswrc).  (Under emacstool, they are all enabled,
and emacs sees sequences starting with C-x *).

They dispatch through the keymap sun-raw-map.  See sun.el, and
$EMACS/etc/SUN-SUPPORT.

This ought to be recurrent comp.emacs posting number 1.  Maybe it
could be the only posting ever in comp.emacs.sun, with an
expire: never.  :-)
