SunSelect, the Sun Microsystems Inc personal computer-to-Unix communications and peripherals subsidiary, was due last night to launch PC-NFS 5.0 for Microsoft Corp’s Win-dows For Workgroups and Novell Inc’s NetWare.

SunSelect also announced SelectMail, an electronic mail product that enables MS-DOS and Windows users to exchange mail files with other personal computers and Unix systems. The new version of PC-NFS adds support for Windows For Workgroups and NetWare device drivers, enabling personal computers to share applications, files, printers and electronic mail across any TCP/IP or Open Network Computing-Network File System network, SunSelect says. It will provide updated device drivers for the next release of Windows For Workgroups. The product continues to support Windows and MS-DOS operating systems. NetWare support also includes Ethernet.
