Hello !

I want to change the parity and the databits at runtime of the UART 0

Here is my code:

RX_RESULT			result;
 RX_URT_HANDLER_UN   unHdlr;


 RX_UART_SET_T myUrt_waeg[] = 

 {	

  {{UART1_NAME,RX_PERIPHERAL_TYPE_UART,0}, // Waegezelle Port             

  0,                                       // Use UART 0               

  RX_UART_BAUDRATE_9600,				   // Baudrate 9,6Kbaud      

  UART1_PARITY,							   // Even Parity              

  UART1_STOPBITS,						   // 1 Stopbit                

  RX_UART_DATABIT_7,				       // 7 Data bits              

  UART_RX_FIFO,                            // No RX-FIFO               

  UART_TX_FIFO,                            // No TX-FIFO               

  RX_UART_RTS_SELF,						   // No RTS in use            

  RX_UART_RTS_ACTIVE_LOW,				   // No RTS in use            

  0,                                       // No RTS forrun            

  0,                                       // No RTS trail             

  UART1_CTS,							   // No CTS in use                

  UART1_CTS_LEVEL,						   // No CTS in use           

  },

  //ptRsc->tLoc.uart=NULL;

    result = rX_MemAllocateMemory(&ptRsc->tLoc.uart, DRV_UART_SIZE);

    if (result != RX_OK)

     while(1); 

    ptRsc->tLoc.uart = malloc(DRV_UART_SIZE);

    result = Drv_UrtCreateUart(ptRsc->tLoc.uart, myUrt_waeg);

   result = Drv_UrtIdentifyUart(UART1_NAME, 0, &ptRsc->tLoc.uart);

   if (result != RX_OK)

	  while(1);   

   

  

  result = Drv_UrtReset(ptRsc->tLoc.uart);

  if (result != RX_OK)

   while(1); 

  result = Drv_UrtInitializeUart(ptRsc->tLoc.uart, 

	 						     UartWaeg_Receive, 

							     UartWaeg_Send, 

						         UartWaeg_Error,

							     pvRsc,

  if (result != RX_OK)

   while(1); 

     ptRsc->tLoc.uartInt = malloc(DRV_INTERRUPT_SIZE);

   result=Drv_IntCreateInterrupt(ptRsc->tLoc.uartInt, &myUart_Int[0]);

   if (result != RX_OK) 

    while(1);

   result = Drv_IntIdentifyInterrupt(UART1_NAME, 0, &ptRsc->tLoc.uartInt);

    while(1); 

  // Interrupt einschalten

  if ((result = Drv_IntEnableInterrupt(ptRsc->tLoc.uartInt)) != RX_OK)

   while(1);

How can I change the "myUrt_waeg[0].eDat" at runtime ?
