There are easier ways for this ... I'd start with virtio-ccw and

Oh. Now _that_ is unexpected.
Then I would not stand in your way.
Still, an uphill struggle; IBM is notorious for not giving out details
about the internals, and simulating a puncher is one of these things.
(And slightly pointless, but who am I to judge ...)
However, I do wonder how you came by an FC analyser ... any chance of me
borrowing it occasionally?

Hannes
