If its a buffered hub, sometimes called a switched hub, or a switch then each connection to the device is really its own collision domain. then when the two talk at the same time one of them gets buffered. By going to half-duplex you are saying you have a straight hub and not the buffering kind. -Michael, who can be wrong and doesn't mind being put straight Alfred Perlstein writes: > * Mike Meyer [001010 09:28] wrote: > > Alfred Perlstein writes: > > > If you have a hub then you'll want to toggle it to half-duplex, if > > > you have a switch, most likely full duplex. > > Could you provide more information about that?

I know how to set these things if I need to. I'm curious about why I would want to use half duplex for a hub vs. full duplex for a switch vs. ??? for two machines talking via an X-over cable. Thanx,
