Yes, But supposedly, you are able to link all Ethernet devices
on the very same wire without having hubs etc. which require
power other than that already provided by the network cards.
When I worked for DEC they called Ethernet "Pandemonium on a wire"
because it’s a lot like a freeway system but only one car can
be on at any one time. But the connection between
everything, is simply a wire (Coax).
Routers are powered devices which must be plugged in.
I am looking Either for a HUB which is not powered
where you just plug all the machines into and let the
Ethernet cards work their miracle or a wiring plan where
you can wire your own junction points.
These Ethernet wires are not just a simple coax today.
Possibly they are not really Ethernet anymore ?
When the Japanese started competing by building
cheaper Ethernet, Dec simply bailed out of the Competition
instead of practicing the expected competitive capitalism.

Is there any way to just plug two machines together
then to the modem without also plugging into a POWER wall socket ?

Also, I'm really having a tough time getting the
two machines to talk (Win7 and WinXP) when I just use
a simple Ethernet cable designed to connect in this way
(like a null modem COM1 cable)

I will look closer at  "Microsoft networking protocol for all computers"
But, still,  First, they need a proper Ethernet Connection.

I also understand you can use any protocol at all
between two machines connected to the Ethernet.
It (Protocol) just needs to be the same on both machines.
But I see no other Protocols to use on a windows machine.

I'm thinking Ethernet is no longer really Ethernet.
Because they do not use Coax anymore.

Thanks for the response.

Hi Geoff -

I have two PCs (WinXP), and a MAC (Snow Leopard - 10.6.7) linked together with ethernet cables, and a Linksys router.  I used the 
basic Microsoft networking protocol for all computers.  I also have three printers linked to the various computers, and available 
for use from the other computers.  I use one of the PCs for WinSDR and seismology, and use the MAC for email and surfing, while the 
other PC is in my wife's office.
