6   Flush the receive FIFO. There is no specific option for this, we 
7   blindly read bytes and discard them. Reading when there is no data
8   is harmless. The 8530 has a 4 byte FIFO, the 85230 has 8 bytes.

11   All locking is handled for the caller. On return data may still be
12   present if it arrived during the flush.
