How to use putty in Uart-to-USB communication?

Hi,

As I mentioned in the previous post, my intention is to have an FPGA counting TTL pulses, and then send the count data to a computer. To visualize it, I mentioned the idea of writing a .txt file with the counting for each interval. What I found from internet is that Uart-to-USB was a way to achieve this, so that's why I made the previous post. The response I got was the one that mentioned the "uart transmit to the putty (usb-to-uart)", however, I'm not entirely sure on what's this step about. I would appreciate some clarification on this process and the steps you mentioned.
