I use it through a serial port.

You may have problem with USB to Serial converters as the soft seems to be only able to connect on Com1 or 2 so you'll have to set you adapter to one of these.
(Go to the Device Manager / ports / your converter then parameters and advanced and set it to COM 1 or 2)
You may have to use the software included to set it properly..

And no, to reply your question I still have no news from Simon
