It worked the first time from Win7 and Sam-Ba 2.11 with the ser 232 to USB converter (from Plugable.com via Amazon) on my HP Folio Ultrabook.
I used the crystal-no-led-full.
Where was it now that I can see if I have the newest ver? I checked the sourceforge.
Now, I backed off opening the calc for the led and I was afraid of making marks after making some tiny ones already. All I have is an led from a TV remote control. Are there some specs as to voltage-resistance etc so I can choose the resistor? I don't have any electronics store around so what I have is what I get.
