Where: n is the delay (in minutes) before the number can be called.
Call Answer Commands
Call Answer commands disable or enable the modem’s AutoAnswer function. These commands
are issued from the DTE. Call Answer commands include Incoming Call (INC), Disregard
Incoming Call (DIC) and Connect Incoming Call (CIC).
Incoming Call (INC)
The INC response informs the DTE that the modem has detected a ring tone. At this point, the
DTE can issue the DIC command to disable the modem from answering the call. INC is similar
to the AT result code RING.
Disregard Incoming Call (DIC)
The DIC command prevents the modem from answering an incoming call. This command is
only valid once the DTE receives an incoming call (INC) response from the modem. A DIC
must be issued within 5 seconds after receiving an INC.
The DIC command format is DIC.
If DIC is issued within 5 seconds, the modem sends the VAL response to the DTE. If DIC is
issued after 5 seconds, INV is returned.
