To Unlock the &V and &Z Commands:
If an administrative password has been implemented, the Hayes-compatible
&V
and
&Z
commands cannot be accessed unless they are first unlocked using the current administrative
password. (
&V
is used to view the active modem configuration, stored phone numbers,
password commands and passwords;
&Z
is used to store phone number, password commands
and passwords). To unlock the
&V
and
&Z
commands, enter
AT &Z1=/ASECURITY
or substitute other current password in place of SECURITY.
The
&V
and
&Z
commands will now be accessible.
To re-lock the
&V
and
&Z
commands, enter
AT Z
. The DTE will respond with
OK
, and the
&V
or
&Z
commands will not function until they are unlocked.
To Program MPP without Callback Operation:
Use the commands
AT &Z
and
/P
to specify the password to be used for MPP without callback
operation. For example, the following command string programs phone cell 5 for MPP without
callback:
AT &Z5=/PYELLOW
The password is YELLOW. After the modems connect, the remote user presses the DTE Enter
key once. The DTE will then prompt the user to enter the assigned password by displaying the
PASSWORD? query. If the user enters the correct password, YELLOW, the call will be
connected.
Note:
MPP passwords may only be stored in phone cells 2 through 49.
To Program MPP with Callback Operation:
Use the commands
AT &Z
and
/P
to specify the callback phone number and password to be
used. For example, the following command string programs phone cell 35 for callback
operation:
AT &Z35=T5551212/PCANARY
The callback number in this example is 555-1212 (with T used to specify tone dialing); the
password is CANARY. A remote user can now call from the specified callback number, 555-
1212. After the modems connect, the remote user presses the DTE Enter key once. The DTE
will then prompt the user to enter the assigned password by displaying the PASSWORD? query.
