PCI modem Netodragon MDV92XP (10b9:5459) not connecting with wvdial

Hello,

I've installed with no problems my Smartlink compatible PCI modem Netodragon MDV92XP (ScanModem identifies it as 10b9:5459) on my Ubuntu 7.10 machine following the instructions given in the Ubuntu wiki.

Now I'm having problems with the connection using wvdial because the modem can't ''catch'' the server answer. In fact, this is what I get:

emanuele@emanuele-desktop:~$ wvdial
WvDial: WvDial: Internet dialer version 1.56
WvModem: Cannot get information for serial port.
WvDial: Initializing modem.
WvDial: Sending: ATZ
WvDial Modem: ATZ
WvDial Modem: OK
WvDial: Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 X3
WvDial Modem: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 X3
WvDial Modem: OK
WvDial: Modem initialized.
WvDial: Sending: ATDT0802201400
WvDial: Waiting for carrier.
WvDial Modem: ATDT0802201400

at this step, about 45 seconds after the server answer (that I can hear without problems), I get on the console:

WvDial: Timed out while dialing. Trying again.
WvDial: Sending: ATDT0802201400
WvDial: Waiting for carrier.
WvDial Modem: NO CARRIER
WvDial Modem: ATDT0802201400
WvDial: No Carrier! Trying again.
WvDial: Sending: ATDT0802201400
WvDial: Waiting for carrier.
WvDial Modem: NO CARRIER
WvDial Modem: ATDT0802201400
WvDial: No Carrier! Trying again.

Here starts an endless loop, as you can guess, and I must stop it with Ctrl-c.

My wvdial.conf is:

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 X3
Modem Type = Analog Modem
Baud = 460800
New PPPD = yes
Modem = /dev/ttySL0
ISDN = 0
Carrier Check = no
Stupid Mode = yes
Phone = 0802201400
Password = *******************************
Username = *******************************

the provider is Infinito, but I've tested also another one, Libero (always using a local POP 080) getting the same results.

I've tried a lot of different strings for 'Init2': adding +MS=34 or +MS=90, substituting &D0 with &D2, erasing &C1, &D2 and/or +FCLASS=0 (in every combination), using ATS11=40 or, finally, copying the 'Init' string inside the '.inf' file of my Windows drivers that make the modem working now. That string is: AT &F E0 X3 V1 &A3 &D2 &C1 S0=0.

All these attempts failed in the same way just described. I'm able to send you ScanModem output, if needed.

Can you help me?

Thank you for reading, and sorry for my bad English.
