screen, it is possible for you to accidentally erase the entry.
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 E
NTER
. 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.
