Parts of this are happening on a pic, so it's not entirly unrelated. I need
the actual specifications for a 10Base-T network. I'm talking about the
actual signals traversing the wire between the card and the hub, not the
packet formats, collision detection, etc. Is there a 10MHz carrier? Do the
two devices simply send serial data at 10MHz, or is some other system going
on here? How does a hub know when a card is connected - is there a certain
keep-alive signal to tell it this, or do the lines have DC voltages to indicate
a connection? I know there's an IEEE spec for this somewhere, but there
has to be some public domain info as well - I'm just unable to find it.
It may also be a possibility to use the AUI interface instead, but I have
the same issue with that - NO information available anywhere I look.

ANY pointers would be greatly appreciated.

Thanks!
