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.
