The A/UX version of tip has a few "features" that are not present in
the BSD version.  Most of them that I've noticed are related to port
configuration and can be worked-around using stty.  It works best if
you're running from a multi-window system such as X or term.  You can
run tip in one window and use stty from the other.  Unfortunately,
there are two sets of terminal configurations you need to worry about:
tip's stdin (/dev/ttypx) and the output port (/dev/tty[01]).  I've
encountered your problem before, but I can't remember what the cause
was.  It was either the ICRNL flag on stdin or the OCRNL flag on the
output port, or both (I hacked both in my version of tip).  From the
other window, after tip is running, you can run "stty -n /dev/ttypx
-icrnl"  or "stty -n /dev/tty[01] -ocrnl".  If you do muck with icrnl,
you'll have to set "el=\r" in /etc/remote, or you'll never be able to
exit tip, because it never sees "<EOL>~.".  You can use this technique
to achieve any arbitrary port configuration on either the input or the
output.  Regardless of the options you use, you don't need to reverse
them when you quit tip, as it should restore your tty to the state it
was in when it started, before either you or tip screwed with the
ports.
