The Chinese have very little idea about the details of how capitalism works in actual practice.
They just are missing those centuries of being immersed in a capitalistic society.

The pre-schoolers running the lemonade stand down the block from me have more instinctive knowledge of running a business in a capitalistic society than a lot of the people selling from the backyard rice paddy do.

True. But if you are lucky, you can snatch items for a price definitely wrong and before they adjust and fix it

OK... Have finally received the correct (1.8V) cable.
Will crack open the PW3 propably next week and attach the Serial.
How to check if it is working? Will LS grant me a file-listing thru Serial?

That serial port is used by, in order:
The SoC boot code built into on-chip ROM ;
The u-boot boot loader ;
The Linux kernel as the operator's console .

All of which produce progress messages.
So if you don't see a flood of output when you power it back up (re-install the battery) - it isn't working.

Yes, once you get to an operator's console command line, "ls" will produce a listing.
Busybox ash is used as the command line shell.

ah, but getting access to that operator's console command line . . . .
All passwords are disabled in the 'main' operating system.
Luckily, these Kindles are dual boot devices.
You have to interrupt the normal boot-up sequence at the start of the boot loader (u-boot) and then use that to boot into the 'diags' operating system.
There is a utility to get the password for user 'root' in the 'diags' OS.
Enter that to reach the command line of that system.
Then mount and modify the 'main' system password file.
Once that is done, you can re-boot back into the 'main' OS and log into that system as 'root'.

The above is only the Cliff's Notes version - don't follow it.
Our best set of serial port user's directions:

All of the gory details are in that thread.

If not running Windows on your PC, you will have to translate the 'how to setup and use' the PC terminal program (Putty) into what you are running.

On the good side -
Learn one and you learn all touchscreen devices (other than Oasis).
All touchscreen devices are the same (other than Oasis), only the image filename changes.

Nobody has found the connection point(s) for the serial port on the Oasis (yet).
