Sampling and UART

Hi, 

I am facing following problems 

1. The  debugger does not go inside the " while (ADC12BUSY & ADC12CTL1 == 1) " at all. I do not know why? Plus the debugger shows me the correct value in Register " ADC12MEM0" but does not show the correct value of variable "SavedADC12MEM0". 

2.  I want to send the ADC sampled values to Tera Terminal. I can communicate with tera terminal well but unable to see the decimal values of the samples.

My code is as follows 

void Port_Init();
void adc_init(void);
void adc_start_Read(void);
void acc_read_with_offset();
void UART(int , int);

volatile int SavedADC12MEM0, SavedADC12MEM1 ;
unsigned int adc_index = 0;
//extern unsigned int SavedADC12MEM0[];

int main(void)
{
WDTCTL = WDTPW+WDTHOLD;

Port_Init();

while (1)
{
adc_init();
adc_start_Read();
// UART();
}
}

void Port_Init(void)
{
P3SEL = 0x30; // P3.4,5 = USCI_A0 TXD/RXD
P6SEL |= 0x80;
P6DIR |= 0x00;
P1DIR |= 0x01;

}

{

REFCTL0 &= ~REFVSEL_3; //Page 693 of data sheet
REFCTL0 |= REFVSEL_2 + REFON; // Configure internal 2.5V reference
