Disable IXON by default based on comment from Eric Norum

<e.norum@sk.sympatico.ca> and concerns from Thomas Doerfler
<td@imd.m.ISAR.de> when he submitted the patch:

  Since enabling XON/XOFF has such a major performance hit on `smart' output
  devices I think it should be *off* by default.  I think some thought should
  be given to adding hooks for hardware that can support XON/XOFF without
  software intervention, or for hardware like the 68360 SCC's that can use
  large buffers, but still handle special characters immediately.

  The patch you sent is a very good start, though.  I just think that the
  software flow control should be off -- to match the way the serial I/O
  support has worked up until now.
