  SVN rev 181993 on 2008-08-22 05:15:52Z by ed
  
  Prevent VSTART flooding when turning on software flow control.
  
  It turned out we transmitted VSTART after each successful read on a TTY
  when software flow control was turned on. This was because of a very
  evil bug where we tested the TF_HIWAT_IN flag the other way around.
