Use the following procedure to call a modem that has callback security enabled.
Note: Autoanswer must be enabled on the calling modem (S0=1 or S0=2).
1. Using a data communication program such as HyperTerminal, dial the number of
the callback modem.
2. When the connection is established, the callback modem responds with a re-
quest for a password.
3. Type the password for your modem, and then press ENTER. You have three at-
tempts to enter a valid password or be disconnected.
4. If the password is valid, the callback modem disconnects. Then, after a short
delay, it calls the number associated with the password and establishes a work-
ing connection.
Note: If you are calling a direct connect number, you must append a hyphen (-) to
the password. If the corresponding phone number has - as its first character, you will
be able to go directly online with the callback modem. If the corresponding phone
number has no - character, you will be prompted for a different password.
