CHAPTER 4: General Operation and Special Features
• Both modems go on-hook.
• The answer modem calls the
originating modem back.
• Modems exchange security
handshake (again) and
connect.

originating and answer modems for
both types of APP are summarized
below and then explained in detail
in the subsequent sections.

• Enter a password in the front
panel password screen of the
originating modem (the user

• A password must be entered in
the front-panel password screen
of the answer modem (the mas-

will do (even a single charac-
ter), except that it should not
be the same as the user pass-
word, and it should not be the
same as any other password
stored in the answer modem’s
memory (for APP or MPP).
APP with callback will not func-
tion if the master password is
removed.
• Use the Hayes AT &Z command
to store the user password and
callback phone number in the
answer modem’s memory.

must be preprogrammed through
the PASSWORD screen of both the
answer and originating modems, as

For APP with callback, do not use
the same password—see
Section
4.12.2 .
