Check by shorting together tx and rx. Then, typing something on the keyboard in putty, you should see the characters being typed.
That test works here, I could see all of my inputs in the terminal when rx and tx were shorted.

Additional info:
the adapter has both a 3.3v and a 5v pin, but I didn't hook either to the kindle because the tutorial says it needs to be 1.8v. Another person told me the other day that you only hook VCC to unpowered boards, so I took that advice, fearing I might fry the kindle.

Thanks.
