GPRS settings
Once you have declared a MS-GSM card, you have to activate the GPRS mode.
When selecting GPRS,
TWinSoft automatically
adapts Initialization and
Operator Phone number
fields (see next).
If the connection requires a
login, select the option
‘The server requires
authentication’.
If you receive a fixed IP
address, declare it in
‘TCP/IP’ tab.
Initialization: You have to add in the initialization string the APN. Replace in the string
the apn
with the URL you receive from your GSM operator.
Example with Mobistar:
AT+CGDCONT=1,“IP”,“WEB.PRO.BE”.
PIN Code: If the SIM card you have inserted uses a PIN code, type it at the place
of the letter n
.
Example:
with the PIN code 4896, you should have in the field: AT+CPIN=“4896”
If the SIM card you have does not require a PIN code, you can leave the
field as it is or erase it.
Operator Phone number: special number to establish the GPRS connection.
Typically, the number is *99***1#. Check with your operator
and type it following the command ATD.
Example with Mobistar, Proximus, SFR, AllIP, …:
ATD*99***1#
Connection at start up: when this option is selected (by default) TB

MS handles the
