Folks,

Anyone using a Sprint phone to connect via dialup?

A friend gave me a phone to try out and I can't connect with it :(

Part of dmesg follows:

usb 2-10: new full speed USB device using ohci_hcd and address 2

I tried to connect to my ISP and use the phone as a modem and I get NO
CARRIER errors all over the place.

root@darkstar:~# cat /etc/wvdial.conf

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem = /dev/ttyACM0
Phone = 7072000
Idle Seconds = 300
Password = 7072000
Modem Type = USB Modem
Stupid Mode = 1
Compuserve = 0
Baud = 460800
Auto DNS = 1
Dial Command = ATDT
Ask Password = 0
ISDN = 0
Username = myusername
Carrier Check = no


For windows I found the following:

Have not tried it because I want to be able to do this under linux OS.
 Should I try another phone?  I just have basic service on the phone
and use it to connect to my ISP using it.  I will traveling to work
and won't have internet access for a good while.

Thanks for any responses/advice/suggestions.

Regards,

Antonio
