PB Config Modem

Bonsoir tout le monde !

Je suis à deux doigts de finir de configurer mon modem ECI Telecom sur mdk 9.2. J'ai installé et configuré les drivers mais quand je connect mon modem à l'aide de la commande
"startmodem | tee log.txt"
il y a un problème à la 4ème phase (sur 5) et ça me donne l'écran suivant :

Using interface ppp0
Connect: ppp0 <--> /dev/pts/1
CHAP authentication failed
Connection terminated.
ioctl(PPPIOCGFLAGS): Inappropriate ioctl for device
