L0208   ATS0     Automatic answer incoming call

The S-parameter command controls the automatic answering feature of the Module. If set to 000, automatic answering is disabled,

otherwise it causes the Module to answer when the incoming call indication (RING) has occurred the number of times indicated

by the specified value; and the setting will not be stored upon power-off, i.e. the default value will be restored after restart.

 

R) ATS0?

a) If success:

<n>

OK

b) If failed

ERROR

W) ATS0=<n>

a) If success:

OK

b) If failed

ERROR

 

<n>

000     Automatic answering mode is disabled. (default value when power-on)

001–255     Enable automatic answering on the ring number specified.

 

NOTE

The S-parameter command is effective on voice call and data

If <n> is set too high, the remote party may hang up before the call can be answered automatically.

000

OK

ATS0=003

OK

 

  

 

L0209   +++     Switch From Data Mode To Command Mode

This command is only available during a connecting PS data call.

This allows entering enter AT commands while maintaining the data connection to the remote device.

E) +++ OK

 

NOTE

To prevent the +++ escape sequence from being misinterpreted as data, it must be preceded and followed by a pause of at least 1000 milliseconds,

and the interval between two ‘+’ character can’t exceed 900 milliseconds.

 

 

 

L0210   ATO    Switch from command mode to data mode 

ATO is the corresponding command to the +++ escape sequence.

When there is a PS data call connected and the TA is in Command Mode, ATO causes the TA to resume the data and takes back to Data Mode.
