These parameters (Initialization string 1, Initialization string 2, Initialization string 3) allow you
to specify a number of command strings that are sent to the wireless module each time a
wireless connection is attempted. These can be used to set non-standard wireless operating
modes.
Each string is prefixed with the characters AT before being sent to the wireless module and
they are sent to the wireless module in the order specified until an empty string is
encountered. For example, Initialization string 3 will not be sent unless Initialisation string 1
and Initialization string 2 are both specified. Initialization strings are not normally required for
most applications as the unit will normally be pre-configured for correct operation with most
networks.
Hang-up string
In a typical wireless application the connection to the network is always on and under normal
circumstances it is not necessary to hang-up the wireless module. Under certain
circumstances however, the router may use the ATH command to try and disconnect the
wireless module from the network, such as if an incorrect APN has been specified and the
module is unable to attach to the network correctly.
This parameter allows you to specify an alternative hang-up string that is sent to the wireless
module when disconnecting a call. As with the Initialization strings, it is not necessary to
include the AT as this is inserted automatically by the router.
Post hang-up string
This parameter allows you to specify additional AT commands that is sent to the wireless
module after it has been disconnected. As with the Initialization strings, it is not necessary to
include the AT as this is inserted automatically by the router.
Listening init string
This is the listening initialization string parameter for external modems.
Listening init interval (secs)
The listening init string is sent at intervals specified by a listening init interval parameter.
Maximum RING count before answering incoming call
The count of the maximum number of rings before answering incoming call can be set in this
field. The default value is 0.
Minimum RING count before answering incoming call
The count of the minimum number of rings before answering incoming call can be set in this
field. The default value is 0.
