The driver functions by managing the advanced hardware features inherent to the 16C950 and 16C954 chips. Unlike standard 16550 UARTs, the 16C95x family offers significantly deeper buffers and faster data rates: Deep FIFOs

: Features automated in-band (Xon/Xoff) and out-of-band (CTS/RTS and DSR/DTR) hardware flow control. Backward Compatibility

: The Rx FIFO may also trigger a timeout interrupt (when less than threshold bytes are pending for 4 character times). The driver must handle this by reading the remaining bytes.
