i follow this thread: <http://linmodems.org/cgi-bin/ezmlm-cgi?1:mss:36960:201009:oiheklhnmlbdpnojhdpi> the modem seems ok, I can see it with gnomePPP, and wvdial, I even connect to it with minicom, but id does'nt play any sound. I even try to let it call my cell phone: I had the call but it was mute. Does a modem wait for a tune, befor emitting sounds? I was expecting to hear something like a fax. Can this explain that the connection ends with a login fail? -- gnome PPP log: -- --> WvDial: Internet dialer version 1.60 --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATX3 ATX3 OK --> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 OK --> Modem initialized. --> Sending: ATM1L3DT7020005002 --> Waiting for carrier.
