RE: xAP - The Proposed Architecture Explained...

["BUTLER, Tony, FM" <roaming@xxxxxxx>]

John, 

that's not at the physical level.  I'm talking hard connectors
here.
If it's ethernet then fine - everything plugs into a hub/switch in a
star
configuration.
If it is serial as seems to be the case here, then do we have a serial
hub/switch or would it be a daiy chain ala 10base-T?
that's what I'm getting at - how will the physical serial port on my
input
device be connected to the serial ports on my 1/2 dozen output devices?

thanks,


Tony
