Hello everyone, I would like to build a "4:1" box that can switch between one of four DEC MMJ consoles. This is so my mini-cluster can have one terminal be the console for four machines. However, I've noticed that sometimes I get a 'break' sent if I simply unplug and plug, so to prevent that I want to make a "hold" circuit such that the VAX will continue to thing a terminal is attached. Any suggestions? --Chuck
