What is it exactly that these connectors do?  Apparently they are more than
just passive devices, somehow indicating that a network is in progress, so
go ahead and crank out 230.4 Kbps?

The serial connection that I have set up is from the Mac's printer port to
the NT's port.  It works; I was just wondering whether it could be working
better...

Any pointers to Apple documents that might provide specifics on these
connectors and/or this type of setup?
