pari.el : Process stty in windows ?

[Ramare]

Dear all,

  [I posted this message on comp.emacs yesterday but this forum seems 
much more active]

  In pari.el under unix/linux, I use the following function:
----------------------------------------------------------------

(defun gp-get-shell (process-name process-buffer-name cmd)
    "Explicit. Aimed at command gp+parameters."
    (let ((process-environment (copy-sequence process-environment)))
      (setenv "TERM"    "emacs")
      (setenv "PAGER"   "cat")
      (setenv "LINES"   "1000")
      (setenv "COLUMNS" (number-to-string (window-width)))
      (start-process process-name process-buffer-name
                     shell-file-name
                     shell-command-switch
                     (concat "stty -echo onlret; " cmd))))
-----------------------------------------------------------------

with cmd = "/usr/bin/gp -s 10000000 -p 500000 --emacs" for instance.

Windows even with gnuwin32 complains quite a lot.
It seems that stty exists but "onlret" is unknown and the ";" does not 
seem to be recognized.

As a matter of fact I am the maintainer of pariemacs, but I have only 
unix at work/home and don't know nothing about windows. it worked well 
for a long time until recently I had a user from the windows world 
trying to get everything to work. The script editing work, only calling 
gp in an inferior shell bugs.

The error message says that "onlret;" is an invalid argument of stty 
(notice the ";").
If we remove the stty part, gp is indeed called but dies with a gentle 
"Goodbye !" (without the prompt even to be seen).


I'm hard put to correct such a thing. So if anyone has an idea, I'll 
edit it for my user. I guess such a patch would be very useful for many 
others, so I'll publish it, though I'm definitely no friend of windows --

Many thanks in advance,
Best, Olivier
