63 ** 09.12.1998 ARG - ESIL 0776 part fix
64 ** The 'RIO_QUICK_CHECK' ioctl was using RIOHalted.
65 ** The fix for this ESIL introduces another member (RIORtaDisCons) here to be
66 ** updated in RIOConCon() - to keep track of RTA connections/disconnections.
67 ** 'RIO_QUICK_CHECK' now returns the value of RIORtaDisCons.
