 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.
