About /dev/ttyS0 appearing not to be a tty, that will not work.
Although it's been over 7 months since I've looked at the ntp code, I
remember being frustrated that the device MUST be a tty because of
that tc{get,set}attr().  I can also remember that I couldn't just hack
it out because it did serve some purpose.
