I have a falcon 40 and got fms to work using ppjoy. I had troubles at first because I was trying to use a serial/usb adaptor. I then tried the cable plugged directly into my serial port with frustration again. Finally I realized that my serial port was disabled in the bios of my computer. Once I enabled it and went through the whole rigamarole the same as Kevinator9 graciously typed, it finally worked.
