Unable to send serial data to PC

I am trying to send the data to UART1 in LP2148. Given below is the code.
But the data displayed is only some junk (mainly ???? is displayed). I am not able to makeout the problem.
The terminal software is configured at 9600 baud. pclk is 15 MHz.

#include <lpc214x.h> //Includes LPC2148 register definitions

#define Fosc 12000000
#define Fcclk (Fosc * 5)
#define Fcco (Fcclk * 4)
#define Fpclk (Fcclk / 4) * 1

#define UART_BPS 9600 //Set Baud Rate here

const unsigned char SEND_STRING[] = "Nex Robotics PVT LTD\nARM7 LPC214x Development Board\nCommunication Test\nSend any character to continue\n";
const unsigned char SEND_STRING1[] = "Test Passed\n";

void Delay_Ticks(unsigned int Delay) //Function to generate finite delay
{ unsigned int i; for(; Delay>0; Delay--) for(i=0; i<50000; i++);
}

void Init_UART1(void) //This function setups UART1
{ unsigned int Baud16; U1LCR = 0x83; // DLAB = 1 Baud16 = (Fpclk / 16) / UART_BPS; U1DLM = Baud16 / 256; U1DLL = Baud16 % 256; U1LCR = 0x03;
}

void UART1_SendByte(unsigned char data) //A function to send a byte on UART1
{ U1THR = data; while( (U1LSR&0x40)==0 );
}

void UART1_SendStr(const unsigned char *str) //A function to send a string on UART1
{ while(1) { if( *str == '\0' ) break; UART1_SendByte(*str++); }
}

int main(void)
{ PINSEL0 = 0x00050000; // Enable UART1 Rx and Tx pins PINSEL1 = 0x00000000; PINSEL2 = 0x00000000;

Init_UART1(); UART1_SendStr(SEND_STRING); while((U1LSR&0x01)==0); UART1_SendStr(SEND_STRING1); while(1) {

} // return(0);
}
