1235          * 2. If these are not enough, you can set any speed using alt_speed as
1236          * follows:
1237          *    - set tty->termios->c_cflag speed to B38400
1238          *    - set your real speed in tty->alt_speed; it gets ignored when
1239          *      alt_speed==0, (or)
1240          *    - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1241          *      follows:
1242          *      flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1243          *      this just sets alt_speed to (HI: 57600, VHI: 115200,
1244          *      SHI: 230400, WARP: 460800)
1245          * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1246          * 3. You can also set baud rate by setting custom divisor as follows
1247          *    - set tty->termios->c_cflag speed to B38400
1248          *    - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1249          *      follows:
1250          *      o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1251          *      o custom_divisor set to baud_base / your_new_baudrate
1252          * ** Step 3 is done courtesy of code borrowed from serial.c
1253          *    I should really spend some time and separate + move this common
1254          *    code to serial.c, it is replicated in nearly every serial driver
