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