[gnu.emacs.bug] Xenix

rms@AI.MIT.EDU (12/03/89)

    I am also running 18.54 under SCO Xenix/386 2.3.2.  I used to have the
    same problem, but if I remember correctly it went away by defining
    HAVE_PTYS and FIRST_PTY_LETTER in src/s-xenix.h (they are commented
    out by default).

If anyone can determine authoritatively whether Xenix has PTYs,
or which versions of it have them, I would like to know.
Then I can provide appropriate s- files.

SCO Xenix 386 version 2.3.2 provides PTY's for use by the "mscreen"
utility, which implements multiple virtual screens on serial
terminals.  I have been unable to find any reference to them in the
manuals except some passing remarks in the mscreen(M) manual page and
in a section in the release notes for 2.3.2 that describes "mscreen".
The release notes talk about the "new" mscreen utility, so one might
assume that pty's are also new (for 2.3.2).  On the other hand, since
they are essentially an undocumented feature there is no real
guarantee that they work or that they won't be replaced by something
else in the next release.  They do seem to work all right with Emacs.
Does anyone have some more accurate information?
