French personal computer-to-Unix house Esker SA has upgraded its Tun Plus TCP/IP and emulation package for accessing network Unix applications from personal computers. New features include Tun SQL, enabling Windows users to run Open Database Connectivity applications with connections to remote databases – currently Oracle, Informix and Sybase – a Netscape Navigator Web browser, facsimile messaging, IBM 3270 emulation and compatibility with Microsoft TCP. The Lyon-based company admitted that its products tend to be used by organisations undecided on their client-server strategies, attracted to fronting old applications with personal computers. Exports accounted for 62% of its ú4m-odd sales last year. It has added offices in Milan, Italy, to those it already has in the US, Canada, Germany and UK. Prices for version 8.0 of Tun Plus, which betas from October 1, are from ú240 – or $400 – per user.
