C-6 Using AT Commands
Setup
Step 1—Set Remote Access Security Passwords
♦
Assign the read-only password, which allows a guest to view
settings only. Use the following command:
AT%P0=[PASSWORD]
♦
Assign the read/write password, which allows a guest to view
and change settings. Use the command format below:
AT%P1=[PASSWORD]
NOTE: Remote access passwords can be up to eight
alphanumeric characters long, and are
not case-sensitive.
To Display Password.
Type %P
n
? where
n
is 0 or 1 to display
passwords
To Disable Password Security.
If you want to disable an assigned
password (and thereby disable remote access security), use the
%
Pn = command to send a blank password, as in the following
examples:
AT%P0=
AT%P1=
Warning
: If you disable the %P1 password, a remote user does
not need to enter a password for configuration access.
Step 2—Enable Remote Access
Set Register S41 for a value of 1 or greater. S41 is used to set the
number of allowable login attempts. A setting of zero allows no
login attempts, and thus disables remote access.
AT S41=1
