<strong>C55</strong>/<strong>C55</strong>I <strong>AT</strong> <strong>COMMAND</strong> <strong>SET</strong> VERSION 1.00<br />
Command <strong>Description</strong><br />
This parameter setting determines the number of rings before<br />
automatic answering.<br />
Parameter <strong>Description</strong><br />
(num)(&W)(&V)<br />
000 (&F)<br />
automatic answering is disabled<br />
001-255 enable automatic answering on the specified ring number<br />
Notes<br />
• This command works for MT data and fax calls.<br />
• Autoanswering of CSD data and fax calls is supported on<br />
ASC0/Mux1 only.<br />
• A CSD call will not be answered automatically if the module is in<br />
GPRS online mode. However, this is possible in GPRS command<br />
mode. The application can detect a call by evaluating the RING line<br />
and distinguish to change into GPRS command mode or stay in<br />
GPRS online mode until GPRS is available again. To answer, to<br />
reject or to wait for automatic answering the incoming call the<br />
application has to switch into GPRS command mode.<br />
• If is set to higher values, the calling party may terminate the call<br />
establishment before the call can be automatically answered.<br />
• The correlation between <strong>AT</strong>S7 and <strong>AT</strong>S0 is important.<br />
Example: <strong>AT</strong>S7=30 and <strong>AT</strong>S0=20 may not allow call establishment.<br />
• Setting is local to the interface. It is allowed to have different<br />
settings on different interfaces. In such cases the interface 'wins',<br />
which is idle and uses the smallest value.<br />
• <strong>AT</strong>SO write command is PIN protected.<br />
• The command <strong>AT</strong>S0 is also used as GPRS compatibility command<br />
to answer automatically to a network request for PDP context<br />
activation (for details see <strong>AT</strong>S0 for GPRS). So using <strong>AT</strong>S0= with<br />
n > 0, will perform a GPRS attach, if the ME is not already GPRS<br />
attached and if ME is configured to do this (see <strong>AT</strong>^SCFG, parameter<br />
). If the GPRS attach fails (e.g. the network rejects the attach<br />
request), the write command returns with error, but the value of <br />
is changed anyway.<br />
The GPRS attach will not be performed on recalling a stored user<br />
profile with <strong>AT</strong>Z or on power up, if a n > 0 setting was stored in the<br />
user profile with <strong>AT</strong>&W.<br />
