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

1092 * 1. Standard baud rates are set in tty->termios->c_cflag
1093 * 2. If these are not enough, you can set any speed using alt_speed as follows:
1094 * - set tty->termios->c_cflag speed to B38400
1095 * - set your real speed in tty->alt_speed; it gets ignored when
1096 * alt_speed==0, (or)
1097 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as follows:
1098 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP], this just
1099 * sets alt_speed to (HI: 57600, VHI: 115200, SHI: 230400, WARP: 460800)
1100 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1101 * 3. You can also set baud rate by setting custom divisor as follows
1102 * - set tty->termios->c_cflag speed to B38400
1103 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as follows:
1104 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1105 * o custom_divisor set to baud_base / your_new_baudrate
1106 * ** Step 3 is done courtesy of code borrowed from serial.c - I should really
1107 * spend some time and separate+move this common code to serial.c, it is
1108 * replicated in nearly every serial driver you see.
