+
+Yup, the bug exists in Ultrix 2.2 as well.  I have reported this bug to
+DEC support every time we get a new release.  I assume that my bug reports
+are getting filed (in the circular file).
+
+It is clear that whoever made this "fix" at DEC had no understanding
+of curses whatsoever.  As in the earlier posting, the bug can be fixed
+by replacing the definitions of the nl() and nonl() macros in curses.h with:
+
+#define nl()    (_tty.sg_flags |= CRMOD,_pfast = _rawmode,stty(_tty_ch, &_tty))
+#define nonl()  (_tty.sg_flags &= ~CRMOD, _pfast = TRUE, stty(_tty_ch, &_tty))
+
+- john nelson.
+
+P.S.  I did reach someone at DEC who would listen (Thanks Chet!)  My
+      understanding is that they have no plans to fix this bug, as curses
+      is now "owned" by some group in England, who is working on a port of the
+      terminfo curses for Ultrix 2.4.  I'm just pissed that my bug reports
+      submitted for Ultrix 1.2 and 2.0 were ignored.
