Chris and Robert:

  I would suggest having a look at the BlackBox web server. Obviously, it
must be doing the right thing.

I am currently using the embedded web server named boa that calls my
executable according to the CGI rules (common gateway interface). In this
executable I am receiving the ASCII string from boa that arrives from the
net. This string is handled by boa, and then it ends up in my CGI
executable. In response, my executable is forming an ASCII text according
to the HTML syntax and I passes it back to boa, which in turn sends it
back to the net. It is a pretty messy process, though it is probably "as
simple as possible".

Having said all this, I personally would not recommend starting from
scratch. I certainly did not. I rather used a demo application that I
downloaded from Analog Devices. The app was sufficiently close to my needs
that I got a head start. I would recommend doing the same thing.

Hope it helps.

Wojtek
