Bercik sent me their config and I'm able to confirm the bad behavior.
But it looks to me as if console messages are swallowed. As soon as I
add sleep() calls around all my writes, they succeed. (Which makes
printf debugging very weird.)

And indeed, if I enter ".1" it continues with "The following device
numbers might belong to CTC or ESCON connections.". So all that happens
is that either Hercules or the kernel while sending swallows the output
and you can't actually see the prompts. That also matches the fact that
there are very few startup messages from the kernel altogether.
Essentially every message that doesn't have a bunch of other messages
following (plus the first of the batch) lands on the console, the other
ones are discarded.

That makes me incredibly suspicious that this is a problem in Hercules.
It's also not in the typescript generated by script(1), so it's not
simply overwriting screen content either. I guess we'd need to either
raise this with the Hercules people or instrument Hercules to see where
the lines are missed.

Kind regards
Philipp Kern
