Section Four - AT Command Set

4.1 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.
4.2 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".
Example:
This command causes your modem to lower its speaker volume.
All default settings are printed in bold text.
