   using the "screen" utility (comp.sources - long ago) to get around
   this problem until our soon to happen upgrade to 5.0.

Upgrading to 5.0 may not help.  When this topic last came up here, the
enclosed article was posted.  We changed our xterm sources to
accommodate, and now we have functional /dev/tty in xterm.  Try it,
you'll like it.  Although this person didn't think the change should
fix xterm, it does, at least under 4.4c.

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).
