   Has anyone tried compiling and running the X11 R4 xterm on a Pyramid 9820?
   I compiled it straight from the MIT tape and everything seems to be fine
   when running it with one exception.
   Whenever I try to run "su" or "passwd" it seems to shoot out extraneous
   CR's.  For example,
   % passwd matth
   Old password: < at this point xterm sends(?) CR before user gets a chance to
		   type
   Sorry.
   It seems that when these programs turn off echo, things get confused
   and a CR is sent.

The actual problem is a Pyr-specific glitch where /dev/tty is not
being attached to your xterm properly.  This has been discussed here
at least a half dozen times in the last couple of years.  Make the
change indicated below to your xterm sources, recompile, and you'll
have a functional /dev/tty in xterm again.

Yes, I can say "cat < /dev/tty" and have it wait till I type. The only change
to xterm in this version was in main.c, where the line

        close(open(ttydev, O_WRONLY, 0));

was changed to
        close(open(ttydev, O_RDWR, 0));

The reason for this eludes me, and I'm not in a position to recompile the
source without the fix, but it seems unlikely that its going to change the
behavior you see. I remember the original article posting the problem stated
they were running OSx 4.4. I've tested this xterm with both 5.0 and 5.1. I
suggest your problem is from an old version of OSx. If you are running a
version 5 and still see the problems, you should report it as a bug (by
sending mail to bugs at pyramid.com).
