I am graduate student in EE at Penn State Univ. In one of the lab here I have to connect microvax and Sun workstation for file transfer. Microvax has VMS and Sun has UNIX . Sun has serial port and ethernet connector . I dont know whether I should build network using ethernet or just connect by serial port. Later on department wants to use Sun or microVAX as a robot controller . If any one out there has done this kind of work please guide me by sending details to SBS@PSUECLB.EDU or SI6@psuvm.edu. Thanks in advance. S. Salvi

Ethernet seems to be a better networking option. If you use serial port, you'll have to deal with multiplexing the serial port later on for expansion. Since your Sun has an ethernet connector, you should explore a microvax ethernet board. Call DEC (800)343-4040 for technical assistance. Michael

(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, PM Lashley CASE Technology, Inc.
