These directions don't appear to be universally applicable - specifically to the Micro and Leonardo correct?  If not how to?

They are universally applicable to boards that have USB-to-serial converters.

The instructions will not work for a Micro or Leonardo.

 The sticky test was developed to be able to test just the functionality of a on board USB serial converter chip, independently of the AVR controller chip being used on the board, for boards that have separate USB and controller chips. On boards that use a AVR controller chip that have built in USB connectivity there is no need for this test.

I did it. It worked (eecchhoo)
I`m having a: "avrdude: stk500_recv(): programmer is not responding" with a NKC Freeduino V2.2 on Ubuntu Studio 13.04
Thanks for the tip. Now I know my serial rig over USB is working.

Did not understand setup #7 "Connect the terminal application to the serial port of your board"  I was using Sketch.....Serial Monitor.

Serial Monitor is a terminal application.  It will work fine for the test.

Is there a loop back test for the Arduino Mega 2560? I don't see a reset pin on it. My tx1 and rx0 are on two different sockets. Unfortunately rx0 is on the ftdi that I use to connect to my PC.

"Start your favourite terminal application.  Serial Monitor will work fine."
What would be a terminal application and how do I monitor the Serial Monitor on the Mega 2560?

I also have a Arduino Uno that I uploaded a sketch to and I ran fine so I'm assuming it's working ok. Does this loop test tell me more about my Uno that I would like to know? I have a reset pin and a tx1 and rx0 on the Digital pins. But again, not to sound stupid but what would be a terminal program and how do you hook up a serial port to test with.

That's the point

The loopback test is to verify operation of the USB/serial chip. If it works there is no need for it

Are you referring to a Mega 2560 board?
