I am going to to give some more testing v4 within next few days. If it works well, I think that it would need just some cosmetic changes. For example, it would be nice to somehow encapsulate the handshake-related code into few helpers. I believe that it might help us to understand and maintain it. Both vprintk_emit() and console_unlock() were too long already before. Best Regards, Petr
