[En-Nut-Discussion] Ethernut 2.1 and web application

[cipo]

HI

I just started my Ethernut 2.1 board and it went smoothly on. I managed to connect via my 
webbrowser and so some simple splash screen from its web server.
I also managed to use the provided COM cable (in the kit) to connect and see some more 
info from the board.

However after some minutes without touching the board or doing anything we now cannot 
connect to the board anymore (using the web browser). I get a blank page instead of the 
previous splash screen with links).
Why is that ? Is there any kind of timeout ?
The led seem ok: steady red, steady yellow and blinking green.

I just need to do some testing reading the I/O lines via the HTTP protocol using my own C 
application (not a web browser) but the browser might be needed for some testing.

Any idea ?
Thank you
