+ * APPLICATION PROGRAMS SHOULD NOT BE USING THESE VALUES. Application
+ * programs should use one of the ftdi_tciflush, ftdi_tcoflush, or
+ * ftdi_tcioflush functions which emulate the Linux serial port tcflush(3)
+ * function.
+ *
+ * History:
+ *
+ * The definitions for these values are with respect to the FTDI chip, not the
+ * CPU. That is, when the FTDI chip receives a USB control transfer request
+ * with the command SIO_RESET_PURGE_RX, the FTDI chip empties the FIFO
+ * containing data received from the CPU awaiting transfer out the serial
+ * port to the connected serial device (e.g., a modem). Likewise, upon
+ * reception of the SIO_RESET_PURGE_TX command, the FTDI chip empties the
+ * FIFO of data received from the attached serial device destined to be
+ * transmitted to the CPU.
+ *
+ * Unfortunately the coding of the previous releases of libfti assumed these
+ * commands had the opposite effect. This resulted in the function
+ * ftdi_usb_purge_tx_buffer clearing data received from the attached serial
+ * device. Similarly, the function ftdi_usb_purge_rx_buffer cleared the
+ * FTDI FIFO containing data to be transmitted to the attached serial
+ * device. More seriously, this latter function clear the libftid's
+ * internal buffer of data received from the serial device, destined
+ * to the application program.
