Hi Simon
yes, I see some messages on ser1. It appears every few seconds, but I get  
the impression there is no answer comming back. I also hooked my PC to the  
LAN with wireshark and there as well, I see nothing originating from my  

tcpecho: When attempting to connect to my board (where tcpecho is running)  
with telnet I get the message

telnet: Unable to connect to remote host: No route to host

I have the feeling its a hardware problem. The LEDs on the switch I am  
connected to with this board also remain dark all the time.
