141 * The 8U232AM has the same API as the sio except for:
142 * - it can support MUCH higher baudrates; up to:
143 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
144 * o 230400 at 12MHz
145 * so .. 8U232AM's baudrate setting codes are different
146 * - it has a two byte status code.
147 * - it returns characters every 16ms (the FTDI does it every 40ms)
148 *
149 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
150 * the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
151 * combinations in both tables.
152 * FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
153 * but I don't know if those ever went into mass production. [Ian Abbott]

1105 * - set your real speed in tty->alt_speed; it gets ignored when

1107 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1108 * follows:
1109 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1110 * this just sets alt_speed to (HI: 57600, VHI: 115200,
1111 * SHI: 230400, WARP: 460800)
1112 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1113 * 3. You can also set baud rate by setting custom divisor as follows
1114 * - set tty->termios->c_cflag speed to B38400
1115 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1116 * follows:
1117 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1118 * o custom_divisor set to baud_base / your_new_baudrate
1119 * ** Step 3 is done courtesy of code borrowed from serial.c
