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.
