We actually plan to use several nto UC on our machines.
These machines can be more than 40 meters long.
Our problem is to connect these devices. Actually the only solution if
we want to use qnet, is to use a 10/100 baseT wiring.
It means to use a switch or a hub to go from the headstock to each
devices distributed along the machine.
The best solution would be to use a 10 base2 but there is lot of
problems with these wires.

Do you plan to port qnet on other technologies?
What kind of transport do you prefer?
QNET itself is designed not to depend on physical transport layer. You can
actually write you own layer once we open the interface (though
I have no idea when this going to happen .
the beta version of the DDK for network drivers was SILENTLY
released … have a look to it.
It should be possible now to develop network drivers which are
using different network media.

I have no precise idea though we have no real choice! maybe IEEE1394.
So, where can I have necessary information to know the QNET API?
How can I develop a transport layer?
I think that I have to use io-net? How can I inform io-net that qnet goes
through IEEE1394?

You concern as originally stated was one of distance. I don’t think that
1394 will do much for you in the way of distance. You could consider
ethernet over fiber if you have a single large span you want to cover. If
you have a lot of controllers down the length of the machine, you could
put 2 ethernet chips on each controller and wire with copper without using
a hub.

how to subscribe to newsgroups of which nobody knows?
By chance I saw the new newsgroups at the weekend…
Well, I don’t know what newsreader your using, but the one I’m
using (something called Outlook Express from some company in
Redmond, Washington) pops up a little dialog anytime someone
adds new newsgroups to the server.

Free Agent, which I use requires you to hit Online, Get New Groups to
update your list – which requires you to know when new ones are
there…Catch 22
Surely your not advocating we rely exclusivly on the behavior of OE as
a justification for anything!

Well, I don’t know what newsreader your using,
Netscape newsgroup reader, because of Outlook Express is
a very unsecure tool…
but the one I’m

Hmm… we try to work in a more or less M$-free zone what means
that only office PCs have installed a few tools from Redmond
… but no tool too much!
