I'm not sure where questions about Xenix should go.  Please
excuse me if this is the wrong news group!

Microsoft advertizes its Xenix 3.0 as being Unix System
III compatible, but I am wondering exactly what they mean
by that.

We run Xenix on an Altos 986-40T, and after upgrading from
Xenix 2.3 (Unix version 7 derived) to Xenix 3.0, I discovered
that in the area of system administration, at least, some things
are still done as in version 7 (e.g., files /etc/ttys and
/etc/ttytype used for port configuration rather than System
III's inittab, gettytab, etc.).  One result is that we can't
configure a modem port to toggle between 1200 and 2400 baud.

I assume that Microsoft's claims mean that all the system
calls of Unix System III are available for programming,
but I imagine that I'm not the only one who expected to
see more of System III than there really is.

I would appreciate any information people have about other
differences between Xenix 3.n and System III, and also
about differences between the new Xenix System V and Unix
System V.  Replies will be summarized for the net.

Thanks!
