Hello all,

Just out of curiosity, has anyone ever seen an implementation for the nine-bit data protocol for async UARTs?  I know the Oxford 950 UART supports nine-bit and I am wondering if a driver has been developed to utilize that.  Specifically, the protocol is where the ninth bit signifies whether the byte is an address byte or a data byte.  I have seen different implementations of this, including storing the ninth bytes in a separate buffer, or identifying the bytes individually, but these have only been in other operating systems.

Thanks!
