Serial port(UART problem) for the new comer

Actually, i want to tell clearly my problem so ,that iam elaborating...please read till the end.........
Actually i am configuring my system baud rate(RS232) t0 19200,8 data bits,1 stop bits,no parity.....

and based on the reset values......

MSEL[5:0]=0x0A; and for BF533 EZkit lite kit CLKIN'Mhz..
so, VCO CLK is:0x0A*27'0MHz...

and on the reset the SCEl=0x05 and DF=0; so,SCLK=VCO/5TMHz.........

Based on the formula Baud rate=SCLK/(16*divisor);
19200T*10^6/(16*divisor);
i found divisor 6(APProximately);

and the program is like this:
i want to first configure serial port 19200,8,1,no
so,UART_LCR=0x0083;//enabling DLAB to access DLL and DLH registers
*pUART_DLL=0x00b0;// 176;
*pUART_DLH=0x0000;
then making DLAB clear so,that i can access THR and RBR registers..

and i want to use polling here not the interrupts so, uam dissabling the interrupts...
just i want to send @ to the BF533 then it will send 'B'..
After wards whatever i will send from system it has to return it....
#include
//#include

void serialin()
{
*pUART_LCR=0x0083;
*pUART_DLL=0x00b0;
*pUART_DLH=0x0000;
*pUART_LCR=0x0003;
}

void main()

{

int a;

serialin();

*pUART_GCTL=0x0001;

*pUART_IER=0x0000;

//polling for whether dat ready signal
//is set or not
while(((*pUART_LSR) & 0x0060) == 0x0060 );
if ((*pUART_RBR)==0x0040)
{
*pUART_THR='B';
while(((*pUART_LSR) & 0x0040) == 0x0040 );

while(1)
{
while(((*pUART_LSR) & 0x0060) == 0x0060 );
a=*pUART_RBR;
*pUART_THR=a;
while(((*pUART_LSR) & 0x0040) == 0x0040 );
}

}

And what's your problem?
