1047 * - set tty->termios->c_cflag speed to B38400
1048 * - set your real speed in tty->alt_speed; it gets ignored when

1050 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1051 * follows:
1052 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1053 * this just sets alt_speed to (HI: 57600, VHI: 115200,
1054 * SHI: 230400, WARP: 460800)
1055 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1056 * 3. You can also set baud rate by setting custom divisor as follows
1057 * - set tty->termios->c_cflag speed to B38400
1058 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1059 * follows:
1060 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1061 * o custom_divisor set to baud_base / your_new_baudrate
1062 * ** Step 3 is done courtesy of code borrowed from serial.c
