Enable automatic answering after specified number of rings.

Notes

This command works for MT data and fax calls.

Autoanswering of CSD data and fax calls is supported on ASC0/Mux1 only.

If <n> is set to higher values, the calling party may hang up before the call is automatically answered.

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

Setting is local to the interface. It is allowed to have different settings on different interfaces. In such cases the interface 'wins', which is idle and uses the smallest <n> value.

The ATS0 write command is PIN protected.

The command ATS0 is also used as GPRS compatibility command to answer automatically to a network request for PDP context activation (for details see ATS0 for GPRS). So using ATS0=<n> with n > 0, will per- form a GPRS attach, if the ME is not already GPRS attached and if ME is configured to do so (see AT^SCFG, parameter <gs0aa>). If the GPRS attach fails (e.g. the network rejects the attach request), the write com- mand returns an error, though the new value takes effect.

The GPRS attach will not be performed on recalling a stored user profile with ATZ or on powerup, if a n > 0 setting was stored in the user profile with AT&W.
