/*
  extshvio.c

  Dispatcher of external DIO functions for estop and general purpose
  DIO using parallel port, linked into 'emcio'. Almost the same
  as extppt.c, except it adds extEstopRead,Write().

  Written for Shaver Engineering Bridgeport mill.

  Modification history:

  7-Aug-1998  FMP changed extInit/Quit to extDio/AioInit/Quit()
  31-Mar-1998  FMP added STG analog IO
  3-Nov-1997 FMP created
