Notes
• This command works for MT data and fax calls.
• Autoanswering of CSD data and fax calls is supported on ASC0/Mux1 only.
• If
is set to higher values, the calling party may hang up before the call is automatically answered.
• The correlation between

is important.
Example: Call setup may fail if ATS7=30 and ATS0=20.

the interface 'wins', which is idle and uses the smallest
value.
• The ATS0 write command is PIN protected.

write command is issued with
attempt to perform a GPRS attach if not yet attached and if configured to do so (due to the setting
="GPRS/ATS0/withAttach","on").
If the automatic GPRS attach fails the ME keeps trying to attach for approx. 5 minutes, before
ends up
with "ERROR" or "+CME ERROR: unknown", though the new
value takes effect. To avoid the risk of long
response times to
in such case take care that the parameter
is off, if autoanswer
mode is not needed for GPRS or if the mobile works in non-GPRS networks.
The GPRS attach will not be performed on recalling a stored user profile with
or on powerup, even though
a value
greater than 0 was stored in the user profile with
