129  *   o 230400 at 12MHz

1191          *      this just sets alt_speed to (HI: 57600, VHI: 115200,
1192          *      SHI: 230400, WARP: 460800)
1193          * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1194          * 3. You can also set baud rate by setting custom divisor as follows
1195          *    - set tty->termios->c_cflag speed to B38400
1196          *    - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1197          *      follows:
1198          *      o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1199          *      o custom_divisor set to baud_base / your_new_baudrate
1200          * ** Step 3 is done courtesy of code borrowed from serial.c
1201          *    I should really spend some time and separate + move this common
