The Xenix's distributed by SCO (for generic *86's), have had version
numbers 2.*.* for the past 3 or 4 years.  The current OS version
is 2.3.*, the current Development version is 2.2.*.  SCO Xenix has
gone through a progressive upgrade from System III-based (with BSD extensions)
to System V-based (ditto) with each new version.

To the best of my knowledge, hardware vendor-supplied Xenix's (Altos,
Tandy, etc.) were originally ported from a Microsoft-supplied, V7-based
Xenix known as Xenix 3.*.  However, I believe these manufacturers newer
386-based machines run a newer Xenix (possibly System V-based).

In all cases (regardless of porting base) Xenix runs a V7-style init/getty
login.  Newer versions have optional inittab login handling.
