Chapter 6 – Callback Security

Direct Connection

Use this procedure when you want to connect without first being called back. The password that you use must be set up for an optional direct connection.

1.Using a data communications program such as HyperTerminal or PhoneTools, dial the number of the callback modem.

2.When the connection is established, the callback modem responds with the following message:

Password>

3.Type a direct connection password, press the - key, and then press ENTER. You have three attempts or one minute to enter a valid password.

4.If the password is valid, the following message appears and the modems establish a working connection:

OK Connecting

Note: You can make all calls direct connect regardless of whether the password or phone number has the - character by using the %H1 command
