Actually, FB's OPEN "C" commands will generally NOT work with serial ports that
are attached to the USB bus.  CommToolbox is the way to go.  My serial port
code works fine with USB-based serial ports.

a serial or ADB workalike, you'll need a custom driver or custome code to talk
to it and FB may be out of luck.
