[SOLVED] Problem in LPC2148 of uart0 and same problem also in uart1

[ratan22]

Can anybody please tell me how to configure UART0 of ARM7 lpc2148. I am trying to communication with pc through max232, i transmit data to pc in 9600 baudrate. i write the program for uart0 and setting the pll value and uart seting but it does not work,i check in the hyper terminal but it blank.
MY PROGRAM:-

#include<lpc214x.h>
 
void pll()
{
 PLL0CON=0X01;
 PLL0CFG=0X24;
 PLL0FEED=0XAA;
 PLL0FEED=0X55;
 while((PLL0STAT&(1<<10))==0);
 PLL0CON=0X03;
 PLL0FEED=0XAA;
 PLL0FEED=0X55;
 VPBDIV=0x01; //pclk=60mhz
}
 
void ser_int()
{
 PINSEL0=0X00000005;
 U0LCR=0X83;
 U0DLL=132;
 U0DLM=1;
 U0LCR=0X03;
}
 
void tx(unsigned char c)
{
while(!(U0LSR & 0x20));
// while((U1LSR&(1<<5))==0);
 U0THR=c;
}
 
int main(void)
{
 unsigned char b;
 pll();
 ser_int();
 while(1)
  {
 b='A';
 tx(b);
 }
}
