* Copy the newly built _kernel8.img_ to the SD card, and then put the SD card into your RPi4
* Make sure your USB to serial TTL cable is connected correctly
* Run PuTTY and double-click your "Raspberry Pi 4" session - you should see an empty black screen and no errors
* Run your terminal emulator (e.g. PuTTY) and connect to the "Raspberry Pi 4" session you set up earlier - you should see an empty black screen and no errors
* Power on your RPi4
If you've followed all these instructions, after a few seconds you'll see "Hello world!" appear in your PuTTY window on your dev machine.
If you've followed all these instructions, after a few seconds you'll see "Hello world!" appear in the terminal emulator window on your dev machine.
_It's a message from your RPi4 to say that your OS is working. Proof at last!_

I don't want this tutorial to just be an explanation so, in the code, you'll see I've added some more functionality to _io.c_ and made use of it in our kernel. Have a read through and see if you can understand what's going on. Refer to the documentation again if you need to.
We can now read from our UART too! If you build the kernel and power on the RPi4 just like before, it'll say hello to the world again. But, after that, you can type into the terminal emulator (e.g. PuTTY) window and the RPi4 sends the characters right back to you.
