This sounds good.  You think the other Magma boards are close enough
to get them working with the same driver, just in case I never come
across this particular board?

I wish there was a driver for the Sun HSI/S board that I have. It looks
to have Zilog parts, but also some asics of some kind too.

It's too bad we can't run SunOS drivers under emulation...

115200 is fine by me... :)

Yes, and I know about the interrupt storms. I run my main terminal at
76800 and it's fine, but it doesn't run like a modem of course.

But I thought I would try it just to see.
