Do not connect the Kindle serial port to a PC serial port.
The Kindle uses 1.8 volt levels, the PC something around 12 volt.
Your Kindle will not survive that combination.
Next, select the sticky thread: "Where do I start?"
Also known as the "Wiki Master Index"
Select "Hardware"
Select "Serial Port"
Use that as a starting point in your reading, rather than searching (although searching is sometimes required, not everything gets indexed).
For a PW-2, see at least:
"Paperwhite 2 serial port connections"
"MicroFTX" serial-to-USB adapter card.
The MicroFTX adapter is now (at least last week) back in stock.
That is the current recommendation - because of its lower cost.
More details about the MicroFTX starting in post #3 of my "KT2 Exposed" thread, see:

Ignore thread title, that same connection pad layout has been used since the K4 through the PW3 released yesterday.
The only difference is the location on the PCB of the connection pad.
Hey, when you have a working, Gerber macro, you might as well use it.
You can take the external 1.8 volt reference from a Li/Fe chemistry battery.

The prior recommendation was to use the FTDI, wire ended, 1v8 interface level adapter cable.
Described here:
http://www.ftdichip.com/Support/Docu...2RG_CABLES.pdf
You want the
TTL-232RG-VREG1V8-WE
model adapter cable.
Just google for it, many distributors sell it.
Also in the master index linked section above you will find DIY level shifter circuit if all you can get is a 5v serial-to-USB adapter.
