List of AT-commands

Commands always start with AT (which means ATtention) and finish with a <CR>

character.

Information responses and result codes

Responses normally start and end with <CR><LF>, except when the modem is set to

“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: <Err> or +CMS ERROR: <SmsErr> strings

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, <CR> and <CR><LF> are intentionally omitted.

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 <CR>.This command makes the

modem repeat the last entered command.The second special command is the “+++”

(also without <CR>).This command is called “escape sequence” and is used when the

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”.
