I just recieved an SCO newsletter and in it they talk about the release
of Xenix 386. They state that Xenix 386 (X386) "is a fully AT&T-System-
V.3-licened version of UNIX System V". I presume that that means
that X386 is an implementation/port of AT&T System V version 3 (SVR3).
Is it?
Does it have STREAMS support?
Does it have RFS support?
Does it have the Transport Interface and Listener service support?
Sounds nice but is it the "real thing" (SVR3)? How might it differ?

I have a beta-test copy of XENIX 386, so it's possible that the final release might differ, though it's hard to imagine how much. From this keyboard, XENIX 386 2.2.1-beta looks like XENIX 286 2.2.1 with demand paged virtual memory and 386 development support, with many (not all) utilities recompiled in 386 mode. It does not support streams, RFS, or any fancy networking, or, at least, the interfaces aren't documented and the kernel doesn't have any symbols which would lead you to believe that they are there. I suspect that the comment above is mild hype, referring to the ultimate migration of SCO XENIX 386 into the Microsoft/ISC/AT&T 386 common OS base, meaning that if it ain't completely V.3 now, it will be upgraded to that over the next year or so. This is all speculation on my part. I don't see the lack of streams, etc., as a big loss for now, though I suppose they are eventually desirable. I will say that anyone running XENIX 286 on a 386 machine is crazy not to be running XENIX 386--the difference in performance is dramatic. The C compiler can generate 286 objects as well as 386 objects, so developers for the 286 are covered. People hacking for their own pleasure will love the 386 environment--all sorts of things which never could possibly work on the 286 (can you say GNU Emacs?) now compile and run. The MH mail system runs wonderfully-- it used to run out of memory all the time in 286 small model and large model was impossible because of the amount of initialized data. -- Steve Dyer dyer@harvard.harvard.edu dyer@spdcc.COM aka {ihnp4,harvard,linus,ima,bbn,m2c}!spdcc!dyer

The following was with our SCO 386, shipping date 30 June, 1987 Special Note to the First Recipients of SCO XENIX 386 Release 2.2 1. SCO XENIX 386 2.2 The Santa Cruz Operation is proud to provide you with SCO XENIX 386 Release 2.2. SCO XENIX 386 is a 5. licensed, SVID conforming version of UNIX System V, specially adapted to the 80386 microprocessor. This demand paging virtual memory native 32 bit mode system requires a 386 based Personal Computer with at least 1Mb of memory. This package is one of the "First Customer Ship" batch. There are a few details to note. // The letter then goes on to list the different packages included in my shipment. I just thought I would let people know what they are saying to the people that get it. As an added note, on or about July 15, I received an updare package from SCO, the was a letter staing to the effect "as you may have noticed there are a few problems with some of the utilities...". Included in the package were about 50 pages of replacement documentation, and disks X1, X2, X3. I have yet to install this set, but I guess it is about time that I do. -- John Michael Mullins CENTEL Business Information Systems, Inc. 5515 Security Lane, Rockville, Maryland, 20852, (301) 984-3636 UUCP: michael@macom1.UUCP or decuac!macom1!michael
