[HECnet] DECnet map, was Re: DECnet/Python

@Paul - found my post from 2019 - looks like I posted the Cisco Ping exchange to c.o.vms and made some folks grumpy: https://groups.google.com/g/comp.os.vms/c/8Yu7SNCu0es/m/dxS93LQDBgAJ Here's the paste of that post: It appears Cisco is sending out a "DNA NSP message: Link service message (0x10)" to which the remote node is responding with "DNA NSP message: Disconnect confirm (0x48)" with "Reason for disconnect: Unknown (0x0029)", constituting one successful "Ping". Can this exchange be done using the NCP command line on OpenVMS?
