PPP > Power-On Configuration 
The Power-On Configuration feature allows you to set an initialization string that will be sent to the modem upon boot 
up.   
 
Power-On Init String Configuration 
Power-On Init String:
  You can enter a string of 0 to 40 characters that will be sent to the modem upon 
boot up. All commands will initialize before you proceed with regular PPP related 
activity. 
 Note:
 When no initialization string is configured, regular functionality of the modem 
is retained.

You must click Save and Restart once you have completed and submitted 
all the screens on which you have made changes. 
 
 
PPP > Modem Commands 
Setting up certain modem commands will allow an external application to query modem information (based on the 
commands entered). The application can use the URL 
HTTP://192.168.2.1/modeminfo.html
 to get the IP address that 
is currently assigned to the wireless modem after the PPP connection is established. It also will show the results of up 
to ten AT commands entered here.   
 
 
These commands will be sent every time a PPP connection to the network is initiated.

GET /atinfor.html HTTP/1.1   
Then press Enter twice.
