Hi Rodolfo,
I've accidentally found your email in the archives of linuxpps list.
Very strange that it didn't come to me directly because I was
subscribed...

This generator sends PPS signals over a parallel port from one computer
to another. So it's just doing what every PPS-capable GPS device does.
I use it to precisely synchronize time on several computers for
distributed real-time simulation. It has very strict timing conditions.
