Looks like part of the message got eaten somewhere.

Yes, I think this'd apply to the Decstations too. So we will need to
support tty's on them.

I think supporting that is part of the reason I did the cs_wr5_{dtr,rts}
stuff. Set them to zero, and the port lacks those pins, so it shouldn't
matter that the other port writes reg 5 (the other part being stuff Apple

Take care,
