  SVN rev 199998 on 2009-12-01 19:14:57Z by ed
  
  Don't allocate an input buffer for a TTY when the receiver is turned off.
  
  When the termios CREAD flag is not set, it makes little sense to
  allocate an input buffer. Just set the size to 0 in this case to reduce
  memory footprint.
  
  Disallow CREAD to be disabled for pseudo-devices to prevent
  foot-shooting.
