This release contains the full set of utilities necessary to run
both XENIX and UNIX System applications (including COFF binaries),
administer the system, install SCO and third-party applications,
edit files, and take full advantage of such features as demand
paging, virtual memory, 4 Gbytes of linear address space, and
32-bit functionality.

Standard features include simplified, menu-driven installation;
the ability to run thousands of XENIX and UNIX System
applications; a powerful, menu-driven system administration
utility; online help; MS-DOS hard disk co-residence and
concurrent MS-DOS and UNIX System V operation with SCO VP/ix;
electronic mail; HoneyDanBer uucp and Micnet networking;
extensive hardware support:  printers, mice, tape drives, modems,
terminals, multiport cards, etc.; link kit installable device
drivers; four command processors:  ksh, sh, csh, and vsh;  vi and
ed editors; SCO MultiScreen virtual consoles; programmable
function keys, including selectable colors and program access to
the hardware bit map;  terminfo and termcap terminal description
databases; and mapchan tty character mapping utility for 8-bit
international peripheral support.


Application

Full application and peripheral support with Release 2.3.2 has
been maintained.  All supported SCO applications and system
software packages have been verified to run under Release 2.3.4.

SCO XENIX 386 is an ideal system for small business, multiuser
computing, point-of-sale systems, or as a platform for turnkey
vertical applications.  Its compact size and low cost make it
