Calling Procedure

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.
