Good points behind this jabbing. DDP would be better if it allowed stuff like this (even with NDA signed). Serial port is the easier part but stuff like JTAG info, cold flashing info etc would be useful.

And BTW, this is off topic but serial port pinout for previous devices are known. I recently got serial working with 770 and N800 (I have two such devices with broken display and both work over serial). It is only about geting ca-42 cable from ebay (mine was US $2.68 including shipping), cutting it and attaching/soldering to right points, no extra HW needed. Just beware that there are two variants of such ca-42 cables, one with more wires that needs extra 3V power (or 5V so they can be used both with 3v and 5v levels) and one with less of them that are powered from USB port and work without extra power and use 3V. If you need such cable, let me know. I have few of them (both good and 'bad' variant) and can point you to ebay seller with high probability of having that easier variant.
