4.15 Commands for Enabling MPP
Modem configuration for MPP is
controlled from the DTE by a
special set of password commands.
These commands are implemented
by using the Hayes
AT &Z
command to store them in
memory. If an administrative
password has been implemented,
the front panel will be disabled and
the AT &Z command will not
function until it (the AT &Z
command) is unlocked. (The
procedure for unlocking the AT
&Z command is explained in
Section 41.6, How to Use Password
Commands
.
The modem incorporates 10
memory locations for storing
telephone numbers, passwords,
and/or the MPP password
commands listed in
Table 4-4 . To

commands are listed in
