1221 	 *      flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],

1224 	 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1225 	 * 3. You can also set baud rate by setting custom divisor as follows
1226 	 *    - set tty->termios->c_cflag speed to B38400
1227 	 *    - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1228 	 *	follows:
1229 	 *      o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1230 	 *      o custom_divisor set to baud_base / your_new_baudrate
