List of AT-commands
Commands always start with AT (which means ATtention) and finish with a
character.
Information responses and result codes
Responses normally start and end with
“short result code format” with the command ATV0, or when the ATQ1 (no result
codes) command is used.
If command syntax is incorrect, an ERROR string is returned. If extended error
result codes are configured (+CMEE) and if command syntax is correct but with some
incorrect parameters, the +CME ERROR:
are returned with different error codes. If the command line has been performed suc-
cessfully, an OK string is returned. In some cases, such as “AT+CPIN?” or
(unsolicited) incoming events, the product does not return the OK string as a response.
In the AT-command list below,
Special AT-commands
In addition to the commands listed below there are two special commands that do not
start with AT.The first command is “A/” without any
modem repeat the last entered command.The second special command is the “+++”
(also without
modem is in dedicated mode (online mode).When entering “+++” in dedicated mode,
the modem will switch from “online mode” to “online command mode”.This means that
it is possible to send commands to the local modem.The escape sequence is useful when
disconnecting the active call.The disconnection is made with the ATH command (see the
list of AT-commands below).The ATO command can also be used when in “online com-
mand mode”.
