Problem Setting up PEC for Serial Comms (C167Cr)

Hi, I basically used the methodology provided by keil on this website.

I am able to set up the PEC and it transmits data out of the Rs232 port. Unfortunately it appears to be transmitting data from a different location than the one I loaded to it (it sends the first byte correctly and all other bytes are 0xFF)! This is my first attempt at using a PEC so I am sure that I am doing something wrong. Here is my code (you will see hacks in it).

void vSendSerData( BYTE *pbBuf, BYTE bLen )
/*******************************************************************************
Description:  This routine sends bLen bytes to the serial port transmitter,
              waiting for the port to empty before sending the next character.
Inputs:  pbBuf - Pointer to byte[s] to send
         bLen - Number of byte[s] to send
Outputs:   NONE
Globals: g_bitCommsType - Indicates Rs485 or Rs232
         g_bitCommsDir - Sets Rs485 direction (transmit or receive)
         m_bTransmitByteCount =  Transmit byte count used by trasmit interrupt
         m_bTransmitByte = Current byte to transmit
*******************************************************************************/
{
static BYTE huge jakdata[5]= "Jerk";
bLen =4;
   /* If this transmission is meant for the Rs485 bus, disable recieve
      interrupts and set the Rs485 line for transmission */
   if (g_bitCommsType == SELECT_RS485)
   {
      ASC_vReceiverDisable();
      g_bitCommsDir = TRANSMIT_485;
   }

   /* Set up PEC 0 (Peripheral Event Controller 0) to:
          increment the source pointer on each transfer,
          set the transfer size to a byte and
          set the number of bytes to transfer to bLen */
   PECC0 = 0x500 | (WORD)bLen;

   /* PEC source pointer is set to the next character in buffer */
   SRCP0 = _sof_(&pbBuf[1]);
SRCP0 = _sof_(&jakdata[1]);

   /* PEC destination pointer is set to serial transmit buffer register */
   DSTP0 = (WORD)&S0TBUF;

  /* enable transmit interrupt */
  /* transmit interrupt priority level(ILVL) = 14 */
  /* transmit interrupt group level (GLVL) = 0 */
  S0TIC = 0x0078;

   /* Set flag indicating that transmission isn't complete */
   m_bTxDone = FALSE;

   /* Put the first byte from the buffer into the transmitter port, PEC 0 will
      process the rest */
//   S0TBUF = pbBuf[ 0 ];
S0TBUF = jakdata[ 0 ];

   /* Wait for the PEC to finish transmitting the message */
   while ( m_bTxDone == FALSE )
   {
      os_delay_task(1);
   }
}/* vSendSerData() */

void vSerialTransmitInterrupt(void) interrupt SERTXINT
/*******************************************************************************
Description:  This is the transmit interrupt handler.  This routine is called
              when a character has been transmitted from the serial port.  The
              routine moves the received character to a recirculating buffer,
              then increments the buffer pointer.  If the buffer pointers are
              equal after the increment, the overrun flag is set.
Inputs:   NONE
Outputs:  NONE
Globals: m_bTransmitByteCount - Pointer to total transmit buffer count
         m_bTransmitByte - Pointer to current transmit buffer index

{
   S0TIC = 0;
   /* Transmission complete, enable receiver if necessary */
   if (g_bitCommsType == SELECT_RS485)
   {
      g_bitCommsDir = RECEIVE_485;
      S0REN = 1;               /* enable the ASC receiver */
   }

   /* Set flag indicating that transmission is complete */
   m_bTxDone = TRUE;

}/* vSerialTransmitInterrupt() */

My map file is as follows:

On page 58 of the Keil C166 Compiler, I can see the following line:
The PEC source and destination pointers are used for PEC transfers and are located in the internal RAM at address 0FDE0H to 0FDFFH. This appears to conflict with the adresses in the map file.

The first line in my main.c file is:
#pragma PECDEF (0-7)

I do not use the PCDEF directive when I compile (should I)?

Any suggestions would be much appreciated.
