116 * The 8U232AM has the same API as the sio except for:
117 * - it can support MUCH higher baudrates; up to:
118 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
120 * so .. 8U232AM's baudrate setting codes are different
121 * - it has a two byte status code.
122 * - it returns characters every 16ms (the FTDI does it every 40ms)
124 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
125 * the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
126 * combinations in both tables.
127 * FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
128 * but I don't know if those ever went into mass production. [Ian Abbott]

889 * Obtaining the actual baud rate is a little tricky since unix traditionally
890 * somehow ignored the possibility to set non-standard baud rates.
891 * 1. Standard baud rates are set in tty->termios->c_cflag
892 * 2. If these are not enough, you can set any speed using alt_speed as follows:
893 * - set tty->termios->c_cflag speed to B38400
894 * - set your real speed in tty->alt_speed; it gets ignored when
896 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as follows:
897 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP], this just
898 * sets alt_speed to (HI: 57600, VHI: 115200, SHI: 230400, WARP: 460800)
899 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
900 * 3. You can also set baud rate by setting custom divisor as follows
901 * - set tty->termios->c_cflag speed to B38400
902 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as follows:
903 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
904 * o custom_divisor set to baud_base / your_new_baudrate
905 * ** Step 3 is done courtesy of code borrowed from serial.c - I should really
906 * spend some time and separate+move this common code to serial.c, it is
907 * replicated in nearly every serial driver you see.
