Well, this does the trick.  However, I am concerned (a) that I am undoing
something that was obviously done on purpose and (b) about the AIX comment,
and I don't have a machine to test it on.  Maybe this hack should be a
HPUX-only thing.

I did finally notice this parenthetical comment in man termios:

  The process group control features described here (except for setting
  and getting the delayed stop process character) are easily implemented
  using the functions tcgetattr(), tcsetattr()...

so it shouldn't have been a surprise, but is that a Posix omission or an HP
one?
