Of course. I'm being thick again ;-)

I'd been thinking about this in terms of display apps over the last
couple
of days, in particular how a Unix program might want to listen, and
drive
several serial devices. In the end, I decided that, in practice, it
meant
one listener program per PC (but that could, of course, drive multiple
serial devices with different config.)

A seperate listner app?
This could then resend the xAP packet to other local ports that other
listeners on the pc could be configured to listen to?

Thanks for info, Mark.
