Web Server Interface
+iWWW - Activate Embedded Web Server
+iWNXT - Retrieve Next Changed Web Parameter
Syntax: AT+iWWW[:n]
Activates W24's internal web server.
Parameters: <n>=Web browser backlog. n represents the number of browsers that can
connect to W24's internal web server simultaneously at any given time.
Note: Each additional browser (over the n number), will close a previous
one and open its own.
Command Options: <n>=1..3
Default: <n>=1
Returns: I/(<Local IP addr>)
where,
<Local IP addr> is the W24 local IP address.
Note: If the web server is already open, then I/(<Local IP addr>) is returned
without any action taken.
In a dial-up environment, W24 goes online and the <local IP addr> is
assigned dynamically by the ISP.
In an WLAN environment, the IP address is assigned by a DHCP server or
configured by the DIP parameter.
I/ERROR If connection to the Internet failed.
Syntax: AT+iWNXT
Retrieves the Parameter Tag name and new value of the next changed
application web parameter, which has not been retrieved since it has been
changed by the remote browser.

When there are no more remaining changed parameters, a blank <CR><LF>
terminated line is returned.
