For SystemV-based machines, change this to "stty -icanon -echo eof=\01 eol=\01".
To return to normal, do "stty icanon echo eof='^D' eol='^@'".

To see the reason behind these shenanigans: look for "MIN and TIME" on
the man page that describes the terminal driver's non-canonical mode.

Sorry, I don't know what is causing the other problem.
