OK, ok... when dealing with packets and WANG's one must now a few things
before connecting the WANG to the network.

When networked, sometimes Wangs operate inside Firewalls that prevent
packets from entering the network in case our system has to interact with
other non-wang (i.e. 3rd party) systems (although want to wang
communication is also possible, albeit non  desirable, unless we are
dealing with a homogeneous wang network using a sender/receiver approach). 

Firewalling is done in order to prevent the wang system to be infected by
malitious virii that might be present in the network. The firewall is also
used to prevent the packets generated by the wang to reach possible 
listening ports operating in the 3rd party system(s) that are present
in the network. When reading the wang packets these ports might spawn
undesired child processes in the 3rd party system(s).

I still wonder why WANG went out of business..... I would imagine the
competition among datacenters around the world for owning the largest WANG
setup. But maybe it was the fact that unlike micro's of the time, people
did not understand why WANG's systems were getting smaller and faster...
