Don't use hardware handshaking! It works, and you could use it, but a
terminal won't (usually) generate enough I/O to necessitate hardware
flow control. Also, it would be one more complication to getting
everything working.

It's done w/ stty. But it should be on. I think the problem is that
the port is coming up in a garbled state, which is a bug present in
all 1.1 ports. The i386 people first mentioned the problem, and
found that "stty sane" seemed to fix things.

Good luck!
