Re: Pluto-P

Hi
I presume that the network card will be dedicated, as the parport is, and
only use a simple packet structure.. If one wants to connect to the
internet, then you'd use a seperate USB link or a second network card if
possible. That way there'll be no surprise jamming.

Right, to make it work for real time, the network segment has to be 
dedicated, and have no possibility of collisions or other traffic.
Forcing the user to add a second net card neatly solves the problem, as 
their on MoBo net jack is still available.
