Thanks, Oleg. A nice work, as usual! I was planning to discover how the restoration works - you saved my time.
FYI we (some persons from CZFREE.net forum) are working on web configurator update - the web pages are going to be stored on USB flash disk for easy debugging. The Client mode should be added to Mode configuration page.
I am also looking for internal expansion connector to be able to connect a serial port to the system bus. If somebody know how to get it, please let me know...
