I do not quite understand what you mean here. Ethernet as I understand it means the IEEE 802.3 protocols, which specify both the physical and data link aspects of network communication. AFAIK, you cannot communicate "below" the physical layer. :) The 802.3 protocols are not "tcp/ip based". Sure TCP/IP can be run on top of them, but the IP spec stops at the network layer, it does not specify anything at the data link or physical layers. Bradley Dunn Harbor Communications
