After more than a year (since Nov 2007) without a personal Internet connection, I decided to finally go ahead and get myself a Tata Indicom CDMA based Internet connection.
The connection speed promised is upto 153.6 kbps ( with a disclaimer that the speed mentioned is subject to network conditions.)
This is how my /etc/wvdial.conf looks like.
Modem = /dev/ttyACM0
Baud = 230400
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2
Init3 = AT+CRM=1
Stupid Mode = 1
ISDN = 0
Modem Type = USB Modem
Phone = #777
Username = internet
Password = internet
The connection speeds is fairly slow with frequent packet drops all along. I am told that the network connection speeds do pick up during the night and non peek hours.
It serves the purpose of checking my emails, doing some research on the web and also for IRC though I find opening sites like YouTube extremely time consuming with this connection.
