186/* ** WARNING ** SIO_RESET_PURGE_RX or SIO_RESET_PURGE_TX are values used
187 * internally by libftdi to purge the RX and/or TX FIFOs (buffers).
188 * APPLICATION PROGRAMS SHOULD NOT BE USING THESE VALUES. Application
189 * programs should use one of the ftdi_tciflush, ftdi_tcoflush, or
190 * ftdi_tcioflush functions which emulate the Linux serial port tcflush(3)
191 * function.
192 *
193 * History:
194 *
195 * The definitions for these values are with respect to the FTDI chip, not the
196 * CPU. That is, when the FTDI chip receives a USB control transfer request
197 * with the command SIO_RESET_PURGE_RX, the FTDI chip empties the FIFO
198 * containing data received from the CPU awaiting transfer out the serial
199 * port to the connected serial device (e.g., a modem). Likewise, upon
200 * reception of the SIO_RESET_PURGE_TX command, the FTDI chip empties the
201 * FIFO of data received from the attached serial device destined to be
202 * transmitted to the CPU.
203 *
204 * Unfortunately the coding of the previous releases of libfti assumed these
205 * commands had the opposite effect. This resulted in the function
206 * ftdi_usb_purge_tx_buffer clearing data received from the attached serial
207 * device. Similarly, the function ftdi_usb_purge_rx_buffer cleared the
208 * FTDI FIFO containing data to be transmitted to the attached serial
209 * device. More seriously, this latter function clear the libftid's
210 * internal buffer of data received from the serial device, destined
211 * to the application program.
