[OT] emulating a hardware synth

So, do you just use this on an untaken serial port and tell VMWare to also 
use that serial port so they would end up virtually connected? I thought 
there was one called echo talk or something using the JFW API on the Windows 
side and simulating an echo synth to whatever is connected to that port.
