How to input Chinese(GB) in Emacs by freewnn-cserver?

[wen@japan.email.ne.jp]

Hi,
I heard that cWnn works well with Mule for input Chinese(GB). 
Does anyone succeed in getting freewnn-cserver works with Emacs20.x to 
input Chinese(GB) in either Potato or Woody? 
This package is developed and maintained by Japanese, but it seems 
neither Japanese nor Chinese has been testing and using it. I could not
find any documentation (even in Japanese) about it and I have tried 
several times but all failed. I am sure the freewnn-cserver is started
but it seems the cserver could not communicate with Emacs.
The following packages were installed in my Woody box:

ii  emacs-dl-wnn   0.4.2-4        Wnn DL module for emacs20-dl
ii  emacs20-dl     20.7-7         The GNU Emacs editor. (Dynamic Loading suppo
ii  emacsen-common 1.4.12         Common facilities for all emacsen.
ii  freewnn-common 1.1.0+1.1.1-a0 Files shared among freewnn packages
ii  freewnn-cserve 1.1.0+1.1.1-a0 Chinese input system
ii  freewnn-cserve 1.1.0+1.1.1-a0 Header files and static library for cWnn

Any help or suggestion will be highly appreciated. I really hope the 
cserver in Debian is a usefull tool to input Chinese in Emacs.
Thanks for your consideration.

Regards,

G.Wen
