When I Send a byte with USART1 on an MSP430F149 It double Sends the

doing something right, anyone know what might cause this phenomenon.
i'm using the USART1 without problems
It sends the second byte about 1 uS after the first, which is faster than
my program does it, ~68uS. So Im pretty sure its something in hardware.
are you sure you're not writing the byte twice to the TXBUF1?
i usualy poll TXEPT to ensure that the last byte was sent:
void putchar(char c) {
while (!(TXEPT & UTCTL1)) {}
TXBUF1 = c;
}
