Hi all, I need to write a simple application that send a message
through Ethernet and get response, I have no idea how to start 
this, I only know how to communicate using Rs-232, my computer
is connected to a local network, can I use this connection for
my Ethernet tests? what should I install? where can I find a 
clear example that shows me how to init the Ethernet, how to send
and how to recieve?

I got some good links from Bob Gonder (Thanks!) and they includ
a source codes for the server - 

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/complete_server_code.asp

and for the client - 

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/winsock/winsock/complete_client_code.asp

but I don't know how to make them work, I copied them to a new
builder project (Builder 4.0, on Windows-2000 PC) and I get lot 
of errors, for example it don't know 'AI_PASSIVE', and it can't 
find the getaddrinfo() function, and lot of other errors, how do 
I make this code working?

I want to run the server code on one computer and the client code
on another computer and to see them talking with each other 
through the local network, can you please help me to complete 
this?

Thanks,
Ori.
