CC430F5137 UART Problem

Other Parts Discussed in Thread: CC430F5137

Hi everyone , 

I am using CC430F5137 and msp430 launchpad as a debugger .  

I used TI sample code for uart. But it does not work . I checked the register and everyting that i should check it .

It seems to be corret .Probably , i  am missing something .

This is the code

For port terminal program , i am using advanced serial port terminal program 

The screen is here 

What does it cause ? 

Or what are the possible errors ? 

Thanks for your help
