I _have_
hacked on the NetBSD driver for it, as I mentioned. Just
because it satisfies _your_ needs doesn't mean it's not
broken-as-designed for, for example, applications wanting normal
RTS/CTS hardware flow control.
Well...not trying to be contrary here, but as someone who uses async
serial pretty much all day, every day, I can't even remember the last
time I needed or used hardware flow control. I can't really speak to
the Z8530's support of that one way or the other.
I needed it for a Commodore 64 that was acting as a console.
