New PPPD = yes

Modem = /dev/ttyACM0

ISDN = 0

Phone = *99***1#

After 'sudo wvdial' command, terminal shows different things includind 'connected' and also shows 'Don't know what to do and hoping for the best' and then PPPD...............
But my system can't connect to internet although the modem works well with Windows XP.
