AHHHHH!   Now I get it!  Finally! sheesh!  I never could "get" this virtual com port / "PORT SPLITTER" thing.  It allows one real HARDWARE port to be accessed by many applications.  Not the other way-round.  
Sort of a software port sniffer octopus style....  par excellence.

a "port already open" killer.

Now THAT makes sence.  Sheesh  Dense-o-ramma some times. 

Dense-o-meter back down to zero.
