Sun Microsystems Inc has new releases of SunLink DNI and TE100, SunNet OSI and PC/NFS. The first two are the products for interoperability between Sun workstations and servers linked to DEC VAX/VMS systems. SunLink DNI 7.0 supports application, data and management-level interoperability between Sun and DECnet VAXes, and SunLink TE100 6.1 supports interactive access to systems that support VT100 terminals so that users can access a VAX/VMS host in a window-based manner instead of having to use a terminal. The X11/NeWS Window System now enables users to access DEC Windows applications transparently and a VMS mail gateway facility has been added. There are programmer interfaces that permit program-level interoperability – DECnet tast-to-task interface and a file access interface.
