Chapter 7 - Callback Security and Remote Configuration

To turn your modem's Callback Security feature on and off:

7.If you want Callback Security with both remote and local password security, enter AT#DB1 and hit RETURN. You must turn on Callback Security to be able to enter dial back phone numbers.

8.If you want Callback Security on with just remote password security, enter AT#DB2 and hit RETURN. You must turn on Callback Security to be able to enter dial back phone numbers. If you want to use your modem to call another modem that is also set for Callback, you must enter AT#DB3 before you dial.

Note: this is for your modem if you are set for #DB1 or #DB2.

Once you have disconnected from that call, your modem will go back to its original setting.

9.If you want Callback Security turned off, type AT#DB0 and hit RETURN.

To set parity of the password/message prompt:

10.The parity default value for your modem is no parity (AT#P0). If your modem's prompt messages use even parity, enter AT#P2 and hit RETURN. For odd parity, enter AT#P1 and hit RETURN.

11.Enter the &W0 command and hit RETURN to store parameters and S-Register values in RAM.
