Abstract

Bidirectional communication between one or more workstations which may be operating on one platform such as UNIX, VAX/VMS or NOVELL'"'"'s NetWare with an event driven database which is operating on a different platform such as QNX is made possible by separating a gateway into two portions with one portion in each platform bidirectionally linked with a pair of BSD socket libraries on each platform.

Claims

1. A glassware forming machine comprising

an event driven database operating on a first platform,

a workstation operating on a second platform and including

application means for making and receiving API (Application Programming Interface) calls,

an event driven database library,

a gateway library and

a BSD (Berkeley Software Distribution) socket library,

said event driven database library bidirectionally interconnecting said application means and said gateway library and

said gateway library bidirectionally interconnecting said event driven database library and said BSD socket library, and

a network gateway operating on said first platform and including

a BSD socket library and

a gateway Service bidirectionally interconnecting said network gateway BSD socket library and said event driven database, and

said BSD socket libraries communicating bidirectionally via TCP/IP (Transmission Control Protocol/Internet Protocol) packets,

wherein said first platform is ONX, and

wherein said second platform is either UNIX VAX/VMS or NOVELL NetWare.
