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.
Ian Abbott8f977e42005-06-20 16:45:42 +0100137 * FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
138 * but I don't know if those ever went into mass production. [Ian Abbott]

Alan Cox464cbb22008-07-22 11:11:23 +0100982 * 2. If these are not enough, you can set any speed using alt_speed as
983 * follows:
Linus Torvalds1da177e2005-04-16 15:20:36 -0700984 * - set tty->termios->c_cflag speed to B38400
985 * - set your real speed in tty->alt_speed; it gets ignored when
986 * alt_speed==0, (or)
Alan Cox464cbb22008-07-22 11:11:23 +0100987 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
988 * follows:
989 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
990 * this just sets alt_speed to (HI: 57600, VHI: 115200,
991 * SHI: 230400, WARP: 460800)
Linus Torvalds1da177e2005-04-16 15:20:36 -0700992 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
993 * 3. You can also set baud rate by setting custom divisor as follows
994 * - set tty->termios->c_cflag speed to B38400
Alan Cox464cbb22008-07-22 11:11:23 +0100995 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
996 * follows:

998 * o custom_divisor set to baud_base / your_new_baudrate
Alan Cox464cbb22008-07-22 11:11:23 +0100999 * ** Step 3 is done courtesy of code borrowed from serial.c
