Chapter 11 – GPRS <strong>Command</strong>s<br />
<strong>AT</strong>+CGD<strong>AT</strong>A=<br />
CONNECT<br />
The mobile is connected using default parameters<br />
(=”PPP” and as described <strong>for</strong> command<br />
<strong>AT</strong>+CGD<strong>AT</strong>A).<br />
The mobile supports Layer 2 Protocol (L2P) PPP only.<br />
Remark: If the mobile is NOT attached by <strong>AT</strong>+CG<strong>AT</strong>T=1 and the CID is NOT activated be<strong>for</strong>e connecting,<br />
attaching and activating is automatically done by the <strong>AT</strong>+CGD<strong>AT</strong>A command.<br />
Some providers (e.g., Vodafone or E-Plus) require to use an APN to establish a GPRS connection. So if you use<br />
the Microsoft Windows Dial-Up Network and <strong>AT</strong>D*9... to connect to GPRS you must provide the context<br />
definition as part of the modem definition (Modem properties/Connection/Advanced.../Extra settings). As an<br />
alternative, you can define and activate the context in a terminal program (e.g., Microsoft Hyperterminal) and<br />
then use the Dial-Up Network to send only the <strong>AT</strong>D command.<br />
11.23 Using the GPRS Dial <strong>Command</strong> <strong>AT</strong>D (Example)<br />
In addition to the GPRS <strong>AT</strong> commands you can use the “D” command to dial into to the GPRS network.<br />
There are two GPRS Service Codes <strong>for</strong> the <strong>AT</strong>D command: Values 98 and 99.<br />
Examples:<br />
<strong>AT</strong>D*99#<br />
CONNECT ‘ Establish a connection by service code 99.<br />
<strong>AT</strong>D*99*123.124.125.126*PPP*1#<br />
CONNECT<br />
Establish a connection by service code 99, IP address 123 and L2P = PPP and<br />
using CID 1.<br />
The CID has to be defined by <strong>AT</strong>+CGDCONT.<br />
<strong>AT</strong>D*99**PPP#<br />
CONNECT<br />
Establish a connection by service code 99 and L2P = PPP.<br />
<strong>AT</strong>D*99***1#<br />
CONNECT Establish a connection by service code 99 and using CID 1.<br />
<strong>AT</strong>D*99**PPP*1#<br />
CONNECT<br />
Establish a connection by service code 99 and L2P = PPP and using CID 1. The<br />
CID has to be defined by <strong>AT</strong>+CGDCONT.<br />
<strong>AT</strong>D*98#<br />
CONNECT Establish a connection by service code 98.<br />
<strong>AT</strong>D*98*1#<br />
CONNECT<br />
Establish an IP connection by service code 98 using CID 1. The CID has to be<br />
defined by <strong>AT</strong>+CGDCONT.<br />
