Now you have to connect to the Kindle from the computer, and control it via Telnet.
Run the PuTTY application (or your Telnet app of choice) and set up a new connection.
Since this will be a Telnet connection, select Telnet under connection type (instead of SSH, which is the default).
You want to connect to 192.168.2.2 (which is your Kindle DX), port 23.
With those Telnet session settings in place, click Open.
You should see a welcome dialog box signaling a successful connection.
Your account will be closed and all data will be permanently deleted and cannot be recovered. Are you sure?
