NCP is the user interface for DECnet configuration, not the network stack.
It is the "Network Control Program", the program to control DECnet
networking.
For example:
NCP> SHOW KNOWN NODES
will show the node known to the node you execute this command on.

What does NCP mean in this context? I thought DECnet NCP meant Network
Control Program, same as in an ARPANET, CHAOSnet, or SNA context.
I.e. a software component now known as "network stack".
