Direct GPRS Connection via PPP
When directly using the GPRS functionality of the GSM/GPRS en-
gine, the INSYS GPRS 5.0 serial will only make PPP raw data avail-
able after the dial-up into the GPRS network has taken place. In this
case, the application must perform the required protocol stacks
(PPP, TCP/IP) for the application. In this mode, the TCP/IP stack of
the INSYS GPRS 5.0 serial is not active.
Example: Connection via the RDT network of a PC.
In this mode, the INSYS GPRS 5.0 serial is the PPP server.

5.4.1 PDP context
With the PDP context, the Access Point Name (APN) of the GPRS
network provider is specified.
Note: see also Chapter 10 "GPRS Dial-in Parameters"
E.g.: The Vodafone APN address is
WEB.VODAFONE.DE.
There is basically the possibility to define different PDP contexts; in
this case it is stored as context “1” (see also Chapt. 6.2.4 “AT com-
mands for GPRS”).
Note: The PDP context can not be stored permanently; it must be

Note: The PDP context can not be stored permanently; it must be
re-entered every time the device is restarted.

5.4.3 GPRS connection setup
Modem-compatible GPRS connection setup
When dialing this special number, the GPRS service is activated.
If a PDP context (AT+CGDCONT) is defined,
such as: The PDP context no. 1, the AT command will be:
The successfully established connection is indicated by the con-
trol signal DCD and the message CONNECT.
After the GPRS connection has been successfully established, the
protocol stacks of the application can start: First the PPP session is
started, and then it can be used for TCP/IP data traffic.
