    Thanks for your response.

    I even built a level adapter with 2 transistors, based on the Arduino S3v3 Revision 2 schematic that like Diavolino outputs directly RXd, TXd and Reset.
    I then connected Diavolino to normal RS-232c on COM1 (XP).
    It does work and I can upload sketches.
    But  I get the avrdude:stk500_disable():protocol error, expect=0x14, resp=0x00   OR 
                        avrdude:stk500_getsync():not in nsync:resp=0x00

    Any hint would help.
