126 * The 8U232AM has the same API as the sio except for:
127 * - it can support MUCH higher baudrates; up to:
128 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
129 * o 230400 at 12MHz
130 * so .. 8U232AM's baudrate setting codes are different
131 * - it has a two byte status code.
132 * - it returns characters every 16ms (the FTDI does it every 40ms)
133 *
134 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
135 * the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
136 * combinations in both tables.
8f977e42
IA		 137 * FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
138 * but I don't know if those ever went into mass production. [Ian Abbott]

464cbb24
AC		 903 * 2. If these are not enough, you can set any speed using alt_speed as
904 * follows:
1da177e4
LT		 905 * - set tty->termios->c_cflag speed to B38400
906 * - set your real speed in tty->alt_speed; it gets ignored when
907 * alt_speed==0, (or)
464cbb24
AC		 908 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
909 * follows:
910 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
911 * this just sets alt_speed to (HI: 57600, VHI: 115200,
912 * SHI: 230400, WARP: 460800)
1da177e4
LT		 913 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
914 * 3. You can also set baud rate by setting custom divisor as follows
915 * - set tty->termios->c_cflag speed to B38400
464cbb24
AC		 916 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
917 * follows:
1da177e4
LT		 918 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
919 * o custom_divisor set to baud_base / your_new_baudrate
464cbb24
AC		 920 * ** Step 3 is done courtesy of code borrowed from serial.c
921 * I should really spend some time and separate + move this common
922 * code to serial.c, it is replicated in nearly every serial driver
923 * you see.
