Well, I dont use (or have) kinternet, but I would presume there is a configuration file for the dialing stuff. If it uses wvdial, its easy. Check to see if you have any data in the /etc/wvdial.conf
Heres a copy of mine:
Note the Dail command line -- that is where your string goes.
Code:
[Modem0]
Modem = /dev/modem
Baud = 57600
SetVolume = 0
Dial Command = ATM0DT
Init1 = ATZ
FlowControl = CRTSCTS
[Dialer CoreComm]
Area Code = 1262
Username = schotty
Password = xxxxxx
Phone = 8276000
Dial Prefix = *70
Stupid Mode = 1
Inherits = Modem0
