There is only one USB to Serial adapter that I have seen that works reliably. It is the Keyspan brand, cost is about $30-$40. That is what I use.SRT,
I got a $15, 9-pin (RS232)-to-USB cable for hooking up the new Haltech F10X. For some reason both of my laptops can't find the right com port or something. Can you tell me what you use to hook up the F10X to a laptop?
