No soldering > involved ;) 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 :-(.
