Commands for Enabling MPP
Modem configuration for MP 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 the
subsequent section titled How to Use Password Commands.)
The ALX modem incorporates 50 phone cells (memory locations) for storing telephone numbers.
Phone cells may also be used to store passwords and/or the MPP password commands listed in
Table 3-1. To implement a security command, use the Hayes
AT &Z command to store the
command in a specific phone cell. The password commands are listed in Table 3-1 and
explained in detail in the sections that follow.
