133 * The 8U232AM has the same API as the sio except for:
134 * - it can support MUCH higher baudrates; up to:
135 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
136 * o 230400 at 12MHz
137 * so .. 8U232AM's baudrate setting codes are different
138 * - it has a two byte status code.
139 * - it returns characters every 16ms (the FTDI does it every 40ms)
140 *
141 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
142 * the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
143 * combinations in both tables.

1125 * - set your real speed in tty->alt_speed; it gets ignored when

1127 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1128 * follows:
1129 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1130 * this just sets alt_speed to (HI: 57600, VHI: 115200,
1131 * SHI: 230400, WARP: 460800)
1132 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1133 * 3. You can also set baud rate by setting custom divisor as follows
1134 * - set tty->termios->c_cflag speed to B38400
1135 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1136 * follows:
1137 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1138 * o custom_divisor set to baud_base / your_new_baudrate
1139 * ** Step 3 is done courtesy of code borrowed from serial.c

1141 * code to serial.c, it is replicated in nearly every serial driver
