UART1- LPC2101

I am doing a project using LPC2101. This is very new for me. So i tried to send one character through UART1. But it is not working. How can i configure External crystal oscillator. Crystal Frequency is 14.7456MHZ. i didnt choose internal or crystal in my code..
INITIALIZATION

PINSEL0 = 0x00050000; /* Enable RxD1 and TxD1*/ U1LCR = 0x83; /* 8 bits, 1 Stop bit */ U1DLL = 96; /* 9600 Baud Rate @ 14.7456MHz */ U1DLM = 0; U1LCR = 0x03;

Plz guide me if my initialization is wrong and give suggestions for me.
