Nice work. Nevertheless one is at least still stuck with the NetX. As
the it has no real EEPROM for the SII data and just emulates it. And
Hilscher apparently forgot to implement the write feature to the
EEPROM (emulated or not). So there is no way in getting the mandatory
information into it.
(At least writing to the EEPROM was not possible when I tested this
half a year ago. I think I will try again with more recent versions of
the firmware.)

That sounds very good.
