Hehe. After some more experiments, it looks like hardware hacking can
not be avoided :-(.
I should have enough connectors, but I don't know the pinouts. I also
seem to have D-SUN USB to TTL from you (thanks again!).
You say TTL, Tony says 3V3... so I guess the port can survive both?
Ok, I guess I really only need to connect GND, and then D- to RXD?
So... where is the D-.. aha, got it. I hope USB has to be robust
enough against me making experiments?
I connected it the best way I could, but I do not get data in minicom,
and RXD led stays lit. I guess that is not a good thing :-(.
