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

1063 * - set tty->termios->c_cflag speed to B38400
1064 * - set your real speed in tty->alt_speed; it gets ignored when

1066 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1067 * follows:
1068 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1069 * this just sets alt_speed to (HI: 57600, VHI: 115200,
1070 * SHI: 230400, WARP: 460800)
1071 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1072 * 3. You can also set baud rate by setting custom divisor as follows
1073 * - set tty->termios->c_cflag speed to B38400
1074 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1075 * follows:
1076 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1077 * o custom_divisor set to baud_base / your_new_baudrate
1078 * ** Step 3 is done courtesy of code borrowed from serial.c
