MSP430G2855: UART connection drops out after power cycle

Part Number: MSP430G2855
Other Parts Discussed in Thread: MAX232

Scenario:

  1. Apply power to PCB / MSP430 
  2. Using Hyperterminal connect to PCB via UART.
  3. Receive data from PCB.
  4. Power off PCB and back on again.
  5. Hyperterminal (HT) no longer receives data, must disconnect in HT and then reconnect.

Ideally I would like to not disconnect and reconnect HT after every power cycle. 

UART setup code is below, clock is 8Mhz, with serial settings 9600, 8N1.

UCA0CTL1 = UCSWRST;
		
UCA0CTL0 = 0x00;
UCA0CTL1 = UCSSEL_2 | UCSWRST;

UCA0BR0 = 65;	
UCA0BR1 = 0x03;	
	
UCA0MCTL = UCBRS_2;
	
P3SEL |= 0x30;
	
UCA0CTL1 &= ~UCSWRST;
