Like I said at the start. I have not tried to identify the problem any 
further. Using llogin to connect to an RSX system works for a while, but 
will disconnect after a while. Exactly when or why is not understood (by 
me at least). But it happens. This is some protocol violation of the 
Linux implementation. It's like they get out of sync, or some packet not 
understood by one side (RSX?) is received.

And when this happens, RSX looses track of a memory buffer, which is an 
RSX error. Given some time, and a few llogin sessions, and RSX will run 
out of memory in the network pool. And the only way to recover is to reboot.

And none of this happens with DECservers, or any other LAT software that 
I have seen.
