does it request address then data characters ? how does it work?
do you send ASCII characters via serial port ? handshaking ? how do i respond to an Ethernet command ? is there a command list ? does it use commands ? i just don't understand it.
can anybody help me ?
Im pretty sure can handle the software and hardware development. i just need to
understand how to communicate via Ethernet
Ethernet simply delivers a packet from one hardware address to another. It doesn't do requests or commands or handshake. You are probably thinking of TCP, which uses IP, which uses Ethernet. If you write a program in Windows or Linux (or some other networking operating system) that opens a socket and talks to another computer, then your program is most likely using TCP or UDP.
Do you really want to learn networking protocols (that's a big project), or do you want to learn to write a Windows or Linux program that opens a TCP or UDP socket and talks to another computer (that's usually easy)?
Ok, a microcontroller project. Forget what I said about Windows and Linux.
I'm guessing that Ethernet won't be sufficient, and you probably also need Internet such as TCP or UDP. Here's an all-in-one chip that provides Ethernet, IP, TCP, and more. I've never tried it. It's looks easy-to-use, but not high-performance: **broken link removed**

Friend I had done a small program using Ethernet - WINSOCK in VB6 using UDP protocol , may be it wiol help you to understand how datatransfer happens in Ethernet .....
