Calling Procedure

Use the following procedure to call a modem that has callback security enabled. 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 request for a password.

3.Type the password for your modem, and then press ENTER. You have three attempts 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 working 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.

8.Press Æ, Æ to go to the ENTER NUMBER #2? LCD.

9.Repeat steps 3–7 to enter the next number.

10.Repeat as many times as necessary, up to memory location 30, until all numbers have been entered.

Warning: There is no way to review an entry to confirm that it has been entered correctly. If you attempt to look at a number entry by pressing the Enter button for an ENTER NUMBER #n? LCD, it is possible for you to accidentally erase the entry.
