The :c:func:`z8530_sync_close()` function shuts down a PIO
channel. This must be done before the channel is opened again and before
the driver shuts down and unloads.
The final supported mode uses a single DMA channel to drive the transmit
side. As the Z85C30 has a larger FIFO on the receive channel this tends
to increase the maximum speed a little. This is activated by calling the
-``z8530_sync_txdma_open
- ``. This returns a non zero error code on failure. The
+``z8530_sync_txdma_open``. This returns a non zero error code on failure. The
:c:func:`z8530_sync_txdma_close()` function closes down the Z8530
interface from this mode.
only code that should need changing are the port I/O functions. At the
moment these assume PC I/O port accesses. This may not be appropriate
for all platforms. Replacing :c:func:`z8530_read_port()` and
-``z8530_write_port
- `` is intended to be all that is required to port this driver layer.
