Hi 

Thank you for your help.

1°) I try to use comint buffer and to launch few commands. I don't
    really understand the way comint works but it seems that each 
    time that I use a command, there is a freeze, and to access 
    back to the emacs  buffer I have to use \C-g several times. 

2°) I put the instruction you suggested. I try to use org-plot/gnuplot 
    and I have the following output on message buffer:

OVERVIEW
org-plot/gnuplot
CHILDREN
Loading d:/perso/home/emacs/emacs-22.2/lisp/org/lisp/org-plot.el (source)...done
script is reset
set title 'Citas'
set yrange [0:]
progn: Wrong number of arguments: (lambda (line) (block add-to-script (setf script (format "%s
%s" script line)))), 2
Mark set

Thanks
