T-Online Script

If you are not the first user of your account, change the number of the
user of this account (Mitbenutzernummer) from 0001 to your number. This
script allows you to input your access number (Anschlusskennung) as a user
ID and your password in the dialog box.

If the service provider computer does not respond, you can increase the

to respond.
