SYNOPSIS

9       void z8530_flush_fifo(struct z8530_channel * c);
10

ARGUMENTS

12       c
13           Channel to flush
14

DESCRIPTION

16       Flush the receive FIFO. There is no specific option for this, we
17       blindly read bytes and discard them. Reading when there is no data is
18       harmless. The 8530 has a 4 byte FIFO, the 85230 has 8 bytes.
19
20       All locking is handled for the caller. On return data may still be
21       present if it arrived during the flush.
