We have a network containing a VAX 11/750, an 11/780, a VSII-GPX,
several other VAXstations, and a Sun 3/160, 3/50, and 3/110.
(And one PC with PC/NFS)

The VAXen are all using VMS.  The Suns are all using un*x.  We have
used three different techniques to transfer data.

1) A serial link and Kermit.
	At 9600 baud, this will consume about 25% of the 780 CPU time.

2) SunLink DNA
	This is a Sun product which provides some communication with
	DECnet over the ethernet.   The current version allows file
	transfer both directions controlled from the Sun, and remote
	login from ether type of machine to the other.  The next
	release (now in Beta test) is purported to support file transfer
	initiated from the VMS machines.  There is ample provision
	(including sample programs) for writing programs to run on the
	Sun using DECnet protocols.

3) TCP/IP on the VAXen
	We are currently in the process of evaluating several TCP/IP
	implementations for VAX/VMS.  These normally provide remote
	login (telnet, sometimes rlogin), file transfer (ftp), and
	electronic mail (VMSmail <--> SMTP) capabilities.


My belief is that the best solution is to have both 2 and 3.  Each
provides its own set of (dis)advantages.

I hope that this has been of some help,
