That older version of rz/sz doesn't do termios, I'm sure.  Since the old 
tip didn't, either, it wasn't a problem.  If you have source, you should 
find it and recompile, making sure that it uses POSIX termios for 
handling tty's.

This is another case of the same.  For some reason, the readline 
configure script doesn't properly tweak things so that termios is used.  
I had fixed this, once, but promptly lost my changes and never got the 
motivation to fix it again.
