<P><FONT SIZE=2>All the problem with that, is that there is no modem involved in that, I have a data acquisition probe, the data visualisation program and my future proxy all on the same ethernet network. And do i need to go at the TCP/IP stack ? I Can't do it at a more highter level ? I just need to read packet on one ethernet card and send them back to another ethernet card after processing and manipulating them.</FONT></P>
