I think that a part of the order programmeur soft must find embarked on
the basis, what would allow actually to order this last one by scripts
and would allow also to update his CUMP by simple download to a RS232
terminal in cases of new version by exemple.
Traduction:
//Je pense qu'une partie du soft de commande du programmeur doit se
trouver embarquée dans la base, ce qui permettrait réellement de
commander cette dernière //par scripts et permettrait aussi de mettre à
jour son CUMP par simple téléchargement à un terminal RS232 en cas de
nouvelles fonctionnalitée..
