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.

Submit: Click the SUBMIT button to save this setting.

Note: 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.

Example of Useful GPRS AT Commands:

AT+CGSN Product Serial Number

AT+CGMR Software Version

AT+CNUM Wireless Subscriber Number

AT+COPS? Network Information (Operator)

AT+CREG? Network Registration

AT+CSQ Signal Quality

Notes:

• You can also retrieve the modem information without using a browser:

Make a TCP connection to port 80 (same as the Web Admin port) and send data as:

GET /atinfor.html HTTP/1.1

Then press Enter twice.

• See the GPRS AT Command Reference Guide (Number S000293x) for other commands.
