9 Bit Transmission

You do not have to use 9 bits. Your standard serial UART will do the job just fine. I mentioned this earlier

You can define your own protocol and use it with normal 8 bit data.

When you use the 9 bit packets, you distinguish address and data bytes by the 9th bit alone. So, any byte having the 9th bit set is an 8bit address byte whereas all words with the 9th bit low are data.
