Commands

AT commands are used to control and configure the operation of the Global Security Modem. AT commands may be issued only from a serial Pass-Thru session from the Sentry or a remote configuration command mode session, if enabled. See Remote Configuration on page 11 for more information on remote configuration sessions.

AT commands may be issued in any combination of uppercase and lowercase. Multiple AT commands may be issued in one line, also known as a command string. Command strings begin with AT and end when Enter is pressed. The following table lists and briefly describes each command.

To set the Setup password:

After successfully logging into the modem with the Setup password, type at#s=, followed by the password and press Enter.

Type atz and press Enter to reset the modem with the new settings.

Example
