    Thanks Bruno,
    I solved that problem.I changed the startup.s file from the working copy and included in my new project.I am able to send the data to hyperterminal with a function which contains the data.

    I am facing one more problme with RTOS(RTX kernel) in keil.I wrote a simple program which creat a task and send data to serialport.before creating the task i initialized the UART.

    I followed RTL-ARM User's Guide to write the program using his RTX kernel and i included configuration file for that and i successfully compiled and i downloaed the code into flash using J-TAG but it is not working.What ever he said in user's guide i followed but it is not working.

    CODE what i was written .

    
#include "LPC23xx.h"
#include "type.h"
#include "target.h"
#include <stdio.h>
#include <RTL.h>

#define CR     0x0D

int sendchar (char ch)  {

  if (ch == '\n')  {
    while (!(U1LSR & 0x20));
    U1THR = CR;
  while (!(U1LSR & 0x20));
  return (U1THR = ch);
}

void PrintDbg(char *str)
{
  while (*str++) {
     sendchar(*str);
  }
}
void  UARTInit(DWORD baudrate)
{
    DWORD Fdiv;

    PINSEL7 |= 0x0000000F;

    U1LCR = 0x83;
    Fdiv = ( Fpclk / 16 )
    U1DLM = Fdiv / 256;
    U1DLL = Fdiv % 256;
    U1LCR = 0x03;
    U1FCR = 0x07;

}

void Init(void) __task
{

   PrintDbg("Hello \n");
   while(1)
     PrintDbg("... PRASAD@OCTI.COM ... \n");
}

int main (void){

  UARTInit(115200);     /* baud rate setting */
  os_sys_init(Init);
  while(1);
  return 0;
}

    I Included RTX_Conf_LPC23xx.c from the keil directory and in Target options i selected the operating system as RTXKernel.

    What might be the reason?why the program is not working.
