That's frustrating.

This looks fine. Except that I need to know the
IP address and network mask of your PC.

But the green LED on the Ethernut flashes on each ping?
You may try ping -t 192.168.0.112

You need to continously send spaces to Basemon to enter the
menu. This is used by Basemon to automatically detect the
baudrate. Just hold down the space bar on the PC. If no
spaces were detected after about 30 seconds, Basemon will
output some information at 34.8 kBaud and automatically start
the webserver.

However, the output you described is from httpd, not from
Basemon.

Did you erase the chip before downloading a new program?
This is done in the STK500 dialog of AVR Studio. The
httpd sample is quite big and have some code left at the
end of the flash ROM, while the beginning contains
garbage. You can only program flash ROM bits to zero,
the chip must be erased to set them back to one.

Ping should work, otherwise http won't.

I've heard about some settings, which disables IE to connect to
Ethernut, but can't remember, what it was. Anyway, ping must
work first.

What is the IP address and network mask of your PC?
