	Certainly.  DECnet-ULTRIX supports task-to-task programming with
	DECnet-VAX (VMS).

	The DECnet-ULTRIX User's and Programmer's Guide is a good start.  The
	Order Number for V3.0 is AA-EA88C-TE.  Chapters 4, 6, 7 and appendixes
	C and D all contain useful information.  The programming examples in
	appendix C can be found in the DNUUNS030 (or DNPUNS030 for DS3100)
	subset.  If you have that subset installed you will find the examples
	in the directory /usr/examples/decnet.

	If you are familiar with using TCP/IP under BSD you should have no problem
	with DECnet-ULTRIX.

	Enjoy!
