Isn't auto speed negotiation based partly on having enough wires, but also partly on sending test packets to see how they fare? To tell you the truth, I never looked into how auto speed negotiation works ... I had the entire factory wired with new cat5 when I moved in (there was no existing ethernet infrastructure) and so it all just works, so I never probed into how it's supposed to back down to 10BaseT, just assumed it did it somehow based on capabilities at both ends of the segment and actual experience. Perhaps the second part of the assumption is wrong.
As to whether it could be added, it depends on the facilities in the ethernet chip (I think Sean posted a link somewhere to the spec sheet) and then if supported at the chip level, someone would have to write the client side "microcode" and a way of setting it up. ... -- Michaelwagner _______________________________________________ Discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
