Serial FIFO: By default, SW550X has its FIFO function enabled to optimize its serial
performance. In some applications (particularly when the flow control is enabled), it may
deem necessary to disable the FIFO function to minimize the amount of data that is
transmitted through the serial interface after a flow off event is triggered to reduce the
possibility of overloading the buffer inside the serial device. Please note that disabling
this option on baud rates higher than 115200bps would reduce the data integrity
noticeably.
Serial Buffer: By default, SW550X will empty its serial buffer when a new TCP
connection is established. This means that the TCP application will not receive buffered
serial data during a TCP link breakage. To keep the serial data when there is no TCP
connection and send out the buffered serial data immediately after a TCP connection is
established, disable this option.
