Section Three - AT Command Set

Executing Commands

Your modem is in Command Mode upon power-on and is ready to receive and execute "AT"

commands. The modem remains in Command Mode until it makes a connection with a remote

modem.

AT Commands & Format

All commands must begin with the AT prefix, followed by the command letter and ended with the

ENTER key. All default settings are printed in bold text. Spaces are allowed in the command

string to increase command line readability but are ignored by the modem during command

execution. All commands may be typed in either upper or lower case, but not mixed. A command

issued without any parameters is considered as specifying the same command with a parameter

of "0".

This command causes your modem to lower its speaker volume.
