Serial is the same.  Imagine a bash shell running on the serial port 
with two VNC client connected and stdio connected.  Utter chaos.  You 
really want to use one or the other, never both at the same time.  If 
that's the case, then just switch the character device on the fly.  
Don't pretend that we can arbitrate multiple clients at once.
