Chapter 2 – AT Commands
Overview
Serial Interface Settings
A modem serial interface is set with the following default values (factory settings):
115,200bps
8 bits data
1 stop bit
no parity
RTS/CTS flow control.
Note: Some models may have a different value for the default baud rate.
The +IPR , +IFC and +ICF commands can be used to change these settings, if required. Changes made using
these commands become effective immediately following the transmission of the successful command result
(OK).
Overview
AT commands are commonly used to communicate with modem equipment. The modem provides an AT
command interface over the serial link between the modem and a host application. The format of an AT command
is an ASCII string that always starts with “AT” and ends with a defined set of characters. The format is defined in
detail later in this chapter.
AT command communication between the host application and the modem is blocking: the host application must
wait for the completion of one command before issuing the next command. The behavior of the modem is
undefined if a new command is issued before the previous command’s result code is returned.
While AT command communication is generally host-driven, unsolicited responses may also be sent to the host
application when a certain events occur. Host applications should be prepared to receive unsolicited responses
from the modem at any time except during AT command entry.
AT+CREG=0<CR>
<CR><LF>
OK<CR><LF>
Unsolicited response cannot occur between the ‘A’ and <CR>
Unsolicited response will not occur here unless otherwise documented
Unsolicited response can occur here
Wavecom supports only the AT commands listed in this document. Other AT commands may be functional as a
result of the baseline code, but they will not be supported by Wavecom. The status of undocumented commands
should not be assumed. It is recommended that only the listed AT commands be used in a host application.
Note: The test command option associated with AT commands may also be present for a large percentage of the
AT commands.
