AT Command Summary
AT commands normally have a number of possible
values. When a command has multiple parameters, the
default is the parameter set at the factory to work with
most applications. Default values for each command
are marked with an asterisk (*).
AT command strings can contain multiple commands in
the same string. These commands are placed after the
AT prefix and before the <ENTER>. Spaces may be used
to separate commands within the string, but no
punctuation is needed except for fax commands. In a
multiple-command line, fax AT commands must be
separated from the following command by a semicolon
(;).
The modem supports the commands listed in this
chapter. AT commands must always begin with the AT
prefix and end with
<ENTER>.
The only exceptions are
the
A/
(Repeat) command or the
+++
escape sequence.
When using the AT commands to dial, you may add
spaces, hyphens or periods to enhance readability.
These characters are ignored.
The notion (
n
) in the command description represents a
numeric option. For example, in the &D
n
command,
n
is a number from 0 through 3. If you issue a command
without a number, the modem assumes 0. For
example, if you type AT&F, the modem assumes AT&F0.
Table 3-1 shows a list of valid AT commands and
provides a page reference for detailed descriptions of
each command.
