I'm currently working with their compiler in a 9-bit application and it definitely does send all 9 bits for me.

You do understand that you have to specify the ninth bit to send seperately, or use the 'long data' flag in the setup (on older compilers, you have to use the former method). You then have to remember that a normal character, will not have nine bits.
It does work, provided you use the long data flag, and send 16bit values to the functions.

Best Wishes
