Dear sir,
I am trying with msp4305529 UART program,but i am not getting the output on hyperterminal.Please go throgh the attachment.
thank you

void uart_send_byte( unsigned char data )

}
void main(void)
{
unsigned int i=0,j=0;
WDTCTL = WDTPW + WDTHOLD; // Stop Watchdog timer
uart_init();
while( 1 )

for (i=0; i<14; i++)

}
for(j=0;j<25;j++)
