In the old days before they could autosense whether a connection was
crossed or not they generally did have a line in.

Well, it was generally called an "Uplink", but from the switch's point
of view there was nothing special about the port (it was just wired
differently)

There's no "in" or "out" there are just ports.

Does this meas that a port can be gained provided that a cross cable is used
to connect another computer ?

Yes. Or you can use a cross cable to cross-connect two switches without
using uplink ports.

Thanks a lot. I was figuring that the uplink was something else, different
from a LAN port.
Wonderful, I've two cascaded switches, both full, this is bringing two ports
more !

You don't always get an additional port. On many switches with an uplink
port. 2 ports are connected to the same wires (just different port pins). If
that's the case, you can't use both ports.

I just had a thourough look, the switches are Zonet ZFS3005.
On the rear, the uplink is close to the port 1.
Below these twioports, a printed white line joins both the port labels ...
That's not mentioned in the user's sheet.
Two bad, too bad :-(

It's counted as one of the ports. That's why 5-port hubs were
common--1 in, 4 out.
