85BPPP > Power-On Configuration
The Power-On Configuration feature allows you to set an initialization string that will be sent to the router 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 router 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 router 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.
86BPPP > 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
HHUUHTTP://192.168.2.1/modeminfor.htmlUUHH to get the IP address that is currently assigned
to the integrated cellular modem after the PPP connection is established. It also will show the results of up to ten AT commands
entered here.
Modem AT Commands Configuration
These commands will be sent every time a PPP connection to the network is initiated.
Example of Useful HSDPA 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 integrated cellular 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 HSDPA AT Command Reference Guide (Number S000453x) for other commands.
