[visionegg] Re: parallel code update: works fine...but

o.k. but that's bad, since then the program code supposes, that there is
a trigger (5V) on the port, even if the port is just in 'rest'.

I want an active high behavior: if nothing is on the port, then 0V else
5V

...? how to achive this? 

I remember that, under windows, the port showed on this line (pin12)
always 0V, I put the trigger on it (5V), the program reacts, trigger
goes to 0... and so on. why doesn't this work the same way under linux?

merci
