The Question is: I have a VAX4000-300 and a VAX 11/785, both running VMS Version 5.4-3, and connected to one another using ethernet. Real-time processes run on both machines and data (not files) are passed between both machines using the facilities provided by DECnet Pha se IV software. I plan to extend the system's capabilities by introducing a PC running Windows NT Version 4 and wish to connect this PC to the VAX 4000 (using the ethernet cable) and setup a process on the PC to exchange data between the PC and a corresp onding process running on the VAX. Any ideas please on what software I need to effect data exchange between the PC and the VAX (in both directions, as fast as possible). Rumour has it there's such a thing as DECnet for Windows NT; is this true and if it is, will it do the job? The Answer is : PATHWORKS 32 is the product that provides DECnet for Windows 95, Windows 98, and Windows NT. But it is unlikely that PATHWORKS 32 V7.1A has been specifically tested with VAX/VMS V5.4-3. Another option for network communications -- one that can operate entirely in parallel with DECnet -- involves the use of IP. (You may have problems finding an IP client for as old a version of the operating system as is in use here.) An OpenVMS upgrade to at least V5.5-2 is recommended, though an upgrade to V7.2 would be better. Also see other topics here, including 4119.
