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! Steve Westfall uucp: ihnp4!gargoyle!west InfotronX, Inc. 159 W. Roosevelt Rd. Phone: 312-231-6054 (ofc) West Chicago, IL 60185 312-852-1271 (home)

Microsoft apparently ported Version 7 and rather than scrap that work and start over for System III, they made it look like System III to the user. Many companies have done this for thier upgrades to System V from System III. A good example is the Unisoft port that I have seen on the Cromemco, NCR and other machines. > 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. I will write later about what I know about Xenix 3 when I get it all together, but let me comment about Xenix System V. It is, apparently, an all new port so it should not be a System V built on the old Xenix. I am very interested in hearing from people who are beta testing the software. I port software for a living and getting burned when people claim a system is one thing and I find out it is another underneath. Sarah Nunke uucp: ihnp4!cosivax!bugs!sln COSI, Inc. 313 N.
