127 * The 8U232AM has the same API as the sio except for:
128 * - it can support MUCH higher baudrates; up to:
129 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
130 * o 230400 at 12MHz
131 * so .. 8U232AM's baudrate setting codes are different
132 * - it has a two byte status code.
133 * - it returns characters every 16ms (the FTDI does it every 40ms)
134 *
135 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
136 * the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
137 * combinations in both tables.
138 * FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
139 * but I don't know if those ever went into mass production. [Ian Abbott]

1044 * follows:
1045 * - set tty->termios->c_cflag speed to B38400
1046 * - set your real speed in tty->alt_speed; it gets ignored when
1047 * alt_speed==0, (or)
1048 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1049 * follows:
1050 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1051 * this just sets alt_speed to (HI: 57600, VHI: 115200,
1052 * SHI: 230400, WARP: 460800)
1053 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1054 * 3. You can also set baud rate by setting custom divisor as follows
1055 * - set tty->termios->c_cflag speed to B38400
1056 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1057 * follows:
1058 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1059 * o custom_divisor set to baud_base / your_new_baudrate
1060 * ** Step 3 is done courtesy of code borrowed from serial.c
