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://xxx.xxx.xxx.xxx/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.
