	I'm actaully working on this as we speak.  After much
going back and forth with WindRiver, they have sent me the two
following fixes:

Fix 1:

====================================================================

#include "vxWorks.h"
#include "sioLib.h"
#include "drv/sio/cd2400Sio.h"

extern SIO_CHAN *sioDesc[];

void evenParitySet(int channel)
    {

    CD2400_QUSART * pQusart;

    pQusart = ((CD2400_CHAN *) sioDesc[channel]) -> pQusart;
    *MPCC_COR1 = COR1_EVEN_PARITY | COR1_PARITY | COR1_8BITS;
    }
 
====================================================================

Fix 2:

=====================================================================
Here is a second version, using sysSerialChanGet:

#include "vxWorks.h"
#include "sioLib.h"
#include "drv/sio/cd2400Sio.h"
#include "sysLib.h"

void evenParitySet(int channel)
    {

    CD2400_QUSART * pQusart;

    pQusart = ((CD2400_CHAN *) sysSerialChanGet(channel)) -> pQusart;
    *MPCC_COR1 = COR1_EVEN_PARITY | COR1_PARITY | COR1_8BITS;
    }
=====================================================================

	I'm just in the process of confirming that these
fixes will work.
