Settings available in this window are:
Use FIFO Buffers - turns the selected ports FIFO buffer on or off. It is strongly
recommended that the FIFO for both ports is left enabled.
Receive Buffer - These settings allow the selection of a receiver FIFO trigger
setting. Selecting a low value will allow the interrupt to be serviced quicker,
which is good for slow machines. If you have a fast machine, setting a high
value will give you more time for multi-tasking operations.
Transmit Buffer - These settings allow the selection of a transmitter FIFO
trigger setting. Selecting a low value will send fewer data-bytes per interrupt,
and this is recommended if you are communicating to a slower machine.
Selecting a high value will send more data-bytes per interrupt, and will give
more time for multi-tasking operations.
