These ports need to be connected to a *USB to TTL* Adapter. In my previous post [How to use Arduino mega as a USB TTL Adapter](https://arshadmehmood.com/hardware/use-arduino-mega-as-ttl-adapter/), I wrote about using **Arduino** as  a **TTL** Adapter. We are going to connect these ports to **Arduino** as below:

### Accessing the terminal with PUTTY

After turning on the **Arduino**, find out the **COM** port from the device manager. 

Enter the following settings in [**PuTTY**](http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html):

In my case the port was *COM3*. Click on open and you should be good to go!
