JP1 Remotes

I was just wondering if anyone could help answer a few questions regarding Pin 6 in a JP1.2/3 remote.

1. When using the JP1.2/3 cables to upload or download, is Pin 6 used for anything?

2. Is it possiible that Pin 6 is dissabled by default in certain remotes, either by the remotes software or hardware?

3. Is it possible to see if Pin 6 is dissabled in the remotes software by using the JP1.2/3 cable and IR.exe or any other software?

4. Is it possible to enable Pin 6 using a jp1.2/3 cable and IR.exe or any other software?

5. Am I correct in saying that Pin 6 is used to send out serial data related to IR commands from the remote?

Any other info related to Pin 6 would be very helpfull.

At thins point in time my questions are actualy related specificaly towards the remote mentioned in the following thread but I am also interested in knowing this answer for all remotes:

If you're asking whether the same data sent to the IR LED is sent via pin 6 of the interface, the answer is no. Pin 6 is the clock signal from the remotes processor. As for exactly what it is or what it is used for, I have no idea. That's why we have Tommy!

It's easy to reach that conclusion by looking some of the schematics. But according to Tommy, who wrote the above linked "A Brief Chronology..."
the actual purpose is different:
With respect to the 6-pin connector, all three types of JP1.x remotes have the following in common:

pin 1 = +3V to +3.3V from remote's power supply
pin 2 = RESET
pin 3 = GND
pin 4 = Serial data to remote (Rx)
pin 6 = Serial data from remote (Tx)

All three communicate at 38400 baud using pins 4 and 6.

So pin 6 carries data from the remote to the JP1.x interface and on into the computer when one is reading from the remote. I think that answers all of the questions in the OP. But if it doesn't, try again. I hope we don't need to make Tommy re-write material.

Thanks for helping to make a little more sense of my Pin 6 questions.
However if possible, I would still likve to know a little more detail on the signals or data sent through Pin 6.

Just out of interest, would anyone happen to know if there is any difference, no matter how small between what or how data is sent through Pin 6 on a JP1.2 comppared to a JP1.3?
