Ce qui me surprends c'est que la commande statserial /dev/ttyS0 fonctionne au demarrage,
mais ne fonctionne plus apres un simple marche arret du modem via systeme-config-network,
Le peripherique doit etre verrouille quelque part non, pourtant /usr/sbin/lsof n'affiche auccune
ligne concernant ttyS0 ?
Ou alors faut-il regarder du cote de la fonction d'ouverture, un simple open() ?
Comment fonctionne exactement l'etablissement d'une connection analogique avec la fedora,
ca semble complique mais un simple script chat devrait suffire non?
