Port info: the serial port parameter.
APN: the APN name of the carrier.
For AT&T, its wap.cingular.
Center Address: Its the server IP address.
If you are using a router, you can use http://whatismyipaddress.com/ to
find out your WAN IP address. In your router, you must use DMZ to point port to
your host LAN IP address.
Port: server port number.
Mode: please always select Center
Heartbeat: The GPRS can periodically send small package to server to
maintain the socket
Running Mode: Support DTU mode and AT command mode.

Send Trigger Mode:
This defines when the DTU will treat the raw serial data as end and send them
over TCP/IP.
There are two modes: timeout and delimit.
If you are using in North America, you must verify the communication band is
set correctly.
In the following, we are going to first set the module into AT command mode,
and check the communication band setting.
Then click DTU option tab, the following window will pop up.
Click Yes.

Use AT+SBAND=7 to move the band to North America bands.
You will see LED101 on eval board start blinking, which means that its on the
network.
This setting is saved even when you power cycle the module.
Now we are done with the communication band setup. We need to exit the AT
command mode by typing: AT+CDTU=1 to enter into DTU mode.
