Actually, this definition isn't true: there is no such error code, 
it's rather imitation.  The fact that author of definition claims 
it's real error indicate that unlike me, he is normal, well

somebody far from being normal and well adjusted. ;)

multiplexing.  Short answer is: no, it's still not possible.
