Next step is activation of the GSM context:
AT#SGACT=0,1, “userid“,“password“
#SGACT: 10.137.93.60
OK

This command replies with the IP address assigned by the network.

Now we can proceed with contacting the server with AT command for socket dial:
AT#SD=1,0,80,”www.telit.com”,0,0

When we receive the CONNECT indication, then we are exchanging data with the HTTP server
program on the remote host machine.

Now following the HTTP protocol we ask for the homepage by sending the following lines on the serial
line:

GET / HTTP/1.1
Host: www.telit.com
Connection: keep-alive

As a response to our query, the HTTP server will reply with the HTML code of the homepage and
some debugging responses that we will see directly on the serial line:

HTTP/1.1 200 OK
Date: Thu, 06 2003 10:21:58 GMT
Server: Apache/1.3.27 (Unix)
Last-Modified: Thu, 06 2003 10:21:58 GMT
Content-Type: text/html
Connection: close

… here is all the HTML code of the page..

+++
OK
AT#SH=1
OK

The Telit module is now back to command mode and the socket is closed.
