4.0 General Operation and Special Features
The modem’s security configuration for password protection is controlled
from the DTE by a special set of password commands. The commands are
implemented by using the Hayes AT &Z command to store them in memory.
If an administrative password is implemented, the AT &Z command will not
function until it is unlocked.
The Modem incorporates 10 memory locations for storing telephone
numbers, passwords, and the password commands listed in Table 4-2. To
implement a security command, use the Hayes AT &Z command to store the
command in a specific memory location. The password commands are listed
in Table 4-2 and explained in detail in the sections that follow.
