I am using an MSP430F1612 and have USART0 set up for SPI 
communications and USART1 set up for UART communications. I checking 
the UTXD1 and UTXD0 lines with a scope and am getting two characters 
out for each single character I put into the Tx buffer. This is 
happening with the spi and the uart. I connected up the UART to 
hyperTerminal on my PC and two characters show up for each one I put 
in. Has anyone seen this problem?

My 2 uarts on my f1612 don't show this phenomenon.

They must all have the same professor.. hahah.. 

I have a question though, how are you connecting the SPI to Hyperterminal 
(ick) and getting anything at all? 

AS someone else mentioned, check your local echo.
