DATA calls reception
Generally in GSM Bulk the automatic answer is disabled (S0=0): in this case the modem
will answer only after it received the ATA command.
In case you want to enable the automatic answer, you must set the S0 register with the
number of rings after which to answer (eg. S0=2 automatic answer after two rings).
GSM Bulk factory configuration has the AT+CBST=0,0,1 setting, in this way it will be able
to answer to any call coming from an analog, ISDN or GSM modem.
[ For further information on the commands, see the chapter "AT Commands" ]
