Hi Pato,
I just ran the eth-to-serial demo on my Tower Vybrid kit with TWR-SER card.
I had setup my RTOS to use interrupt mode for the UART. For my Rev F board that is "ittyb". Your board revision might have a different UART as FYI.
I plugged into my home network that also uses 192.168.1. as the gateway/router. I pinged the 192.168.1.202 to make sure no other device was using it.
Then I ran the eth-to-serial demo and got the following:
Waiting for the incoming connection...OK
Then I pinged it from my laptop and got:
Sending ICMP ECHO REQUEST to module
Received ICMP ECHO REPLY
Then when I did the connect to the 192.168.1.202:23 the Terminal showed:
Serial <-> Ethernet bridge
And the TCP window showed:
Connecting to 192.168.1.202 ...
Connected to 192.168.1.202
Ethernet <-> Serial bridge
If I type something in one window it will show up on the other (unfortunately there was no echo back to the window I type from so that can be confusing).
If you still have issues you might refer to the following Doc Section 7 to make sure your jumpers are configured correctly:
