Re: Max Devices on ethernet adapters

[michaelr_41@xxxxxxxxxxxxxx]

And then you put in switches or you break it into subnets and route
them...

Twinax is a fine physical protocol for what it does...LU6.2 and LU7 and
PU2.1 are great too...TCP/IP and Ethernet is not the best...just the most
widely used. M$ Windows isn't the best OS, it's the most widely used.
