Hello,
from
http://pinouts.ru/data/siemens_c55_pinout.shtml
i have learned, data cables for newer SIEMENS mobilephones ( like x65 series ) are using USB.
Does this mean, serial asynchron in/out ( like with elder models ) no longer is available or is this depending on status of control inputs?

It is available, like with older models. Schematic is the same. But x65 can comunicates with PC by USB cable without any chips, only with 2 or 3 resistors 10k.
