.SH "DESCRIPTION"
.PP
Flush the receive FIFO\&. There is no specific option for this, we blindly read bytes and discard them\&. Reading when there is no data is harmless\&. The 8530 has a 4 byte FIFO, the 85230 has 8 bytes\&.
.PP
All locking is handled for the caller\&. On return data may still be present if it arrived during the flush\&.
