Entering the Selected Password
When the new password is correctly
displayed on the LCD, press the
ENT pushbutton. This will cause
the new password to take effect.
The modems are configured
for APP without callback when
matching passwords are entered
in the front panel password screens
of both modems.

THE ASSWORD WITH

UMBER
If you have followed these instruc-
tions to this point, the user
password will be stored in the
front-panel password screen of the
originating modem, and a different
password (the master password)
will be stored in the front-panel
password screen of the originating
modem, and a different password
(the master password) will be
stored in the front panel password
screen of the answer modem. (The
master password should be
different from the user password,
because it can be used to access the
answer modem directly, without
callback. The master password
allows access for troubleshooting
from a remote site.)
The final step in configuring the
modems for APP with callback is
to store the user password in the
answer modem's memory, along
with the callback phone number,
as explained below.
CHAPTER 4: General Operation and Special Features
C : S
ALLBACK TORING

From the DTE, use the Hayes AT
&Z command and /S (a special
command) to store the user
password (capital A through Z, no
spaces) and callback number in a
specific memory location. Memory
locations 0 through 9 may be used.
The following example shows how
to store a user password and
callback number in memory
location 3:
Enter AT &Z3=T5551212/SGRAPE
The callback number (phone
number of the originating modem)
in this example is 555-1212 (with T
used to specify tone dialing). The
user password is GRAPE. (When
the user password is entered on the
front panel password screen of the
originating modem, a space is
required at the end. Do not use a
space at the end when storing the
password with the AT &Z
command.)
A remote user can now call from
the specified callback number, 555-
1212. The originating modem will
send the preprogrammed password
GRAPE as part of the security
handshake. The answer modem
will confirm the password and
connect by calling the originating
modem back.
