	<netdnet/dn.h>, <netdnet/dnetdb.h> and dnet_conn(3dn) are
	DECnet-ULTRIX include files and subroutines (ie. they are
	specific to DECnet-ULTRIX's implementation of DECnet).

	dnet_conn(3dn) is used to establish a connection to a
	specified remote node/object.  Just replace the call
	to dnet_conn(3dn) with SunLink DNI's equiv routine
	(or set of library/socket calls).

	In the interm (ie. before you modify the X sources) if you
	need to pop up windows between your VMS systems running
	DECnet and your Sun system's running TCP/IP, and you have
	a nearby DECnet-ULTRIX node running V3.0 or later, install
	the unsupported subset and then take a look at the README
	file in the /usr/examples/decnet/gatethru directory.  It
	will tell you how to use the example program in that directory
	as a transport level bridge between DECnet and TCP/IP for
	the purpose of talking X11.
