The NS16550 will sometimes transfer extra characters when the CPU reads the RX FIFO. Due to the asynchronous nature of this failure there is no work-around and the NS16550 should NOT be used in the FIFO mode. The NS16550A has no problems operating in the FIFO mode and should be used on all new designs.}}</ref>
