When the "rtnet start" is in proccess I can't even "Alt+F2" to other consoles The rate of the message if irregular.. sometime it outputs 2 at a time and sometimes none till few secs. > > .. > > What is RTcap suppose to show when up and working ?

So it won't be in any use if I can't get two machines communicating ?

How do you transmit and receive data remotely without having RTmac and RTcfg ? a rt Ethernet driver or a normal one? I have checked out what that "unknown layer-3 protocol" mean.. But I am not sure how this error can still occur if in the manager it store all the possible protocl in a stack (or is it a queue?)
