I cant get this to work. I only want to turn on a led if I recive
something on UART1. 
This is the code:

void init_serial (void)      // Initialize Serial Interface  
{ 
	unsigned dummy;
	unsigned short baud = 9600, baud_rate;     

	PINSEL0 = 0x00050000;    /* Enable RxD1 and TxD1 */
	
	U1LCR = 0x0D3;            /* 8 bits, no Parity, 1 Stop bit */
	U1IER = 0;               /* Disable UART1 Interrupts */
	
	VICVectAddr0 = (unsigned long)ElsyIRQ;
	VICVectCntl0 = 0x20 | 7; /* UART1 Interrupt */
	VICIntEnable = 1 << 7;   /* Enable UART1 Interrupt */

 	baud_rate	  = UART_BAUD(baud);
	U1DLL 		  = (signed char)(baud_rate);			//LSB
  	U1DLM 		  = (signed char)((baud_rate) >> 8); //MSB 
 	U1LCR 		  = 0x00000003;              // DLAB = 0 

	dummy = U1IIR;   /* Read IrqID - Required to Get Interrupts Started */
	U1IER = 3;       /* Enable UART1 RX and THRE Interrupts */

}

void ElsyIRQ (void) 
{
	IOSET1 = 0x000F0000;           // Turn on LEDs
	VICVectAddr = 0x00000000;
}

Can someone please help me?

Hmm, very strange! Now it works without any changes....

Thanks anyway!

A quick observation; the IO pin direction will most likely need to be set
as an output and it's function may possibly need to be set to GPIO.

Yes, sorry I did that in the main function...
