TCP/IP Networking UniFLEX: The Total Solution

Technical Systems Consultants, Inc. is pleased to A variety of solutions exists for system designers announced complete TCP/IP networking support looking for off-the-shelf system software for for its popular UniFLEX® real-time operating real-time microcomputer applications. system. The networked version of UniFLEX runs on all GMX computers based on the 68020 and One approach is to use a full-featured operating 68030 processors. It is fully compatible with the system for normal tasks in conjunction with a new GMX Ethernet board (SBC-EN) as well as the more limited real-time "executive" to monitor Arcnet board (SBC-AN). real-time tasks. With this arrangement, however, the designer is often forced to do A full range of networ« utility programs or application coding and compilation under one "services" come with the system, including: system then migrate to a different system for test and debug. Needless complexity is added to the FTP - File transfer program design process. Telnet - Remote login utility Sendmail - Remote Mail utility UniFLEX, however, provides the total solution in RSH - Remote program execution one . UniFLEX is a multitasking, Talk - Interactive network conversations mUltiuser, -style operating system designed specifically for real-time applications. Features Built into the basic system is the ability to such as demand-paged virtual memory, automatically route data between networks. This hierarchical file system, TCP/IP and NSF means that a installations with multiple local networking, plus System V compatible libraries networks can be logically connected. And because make UniFLEX the perfect choice for a multiuser auto-routing is part of the underlying network software development enviroment. Special system, network users do not need to execute any features such as the separate real-time task list, special commands to utilze this feature. shared data pages, intertask message exchanges, and contiguous file support provide a solid base on which to build any high-performance real-time application.

UniFLEX comes complete with a command shell, file-system, and device independent 1/0, as well as editor, relocating 680201030 macro assembler, quick debugger, and Make-style utility. Options include a C , source-level debugger, several third-party languages and public-domain The figure above illustrates two Ethernet local editors and programming tools. networks connected by an Arcnet which can run upto 8 Km in length without a repeater. UniFLEX has been ported to all GMX 68020 and 68030 based systems. It works with most GMX Also included with the network package is a add-in boards including the DMA SCSI, Ethernet, library of C functions based on the BSD socket Arcnet, and serial 1/0 boards. For more mechanism. This greatly simplifies the task of information on making UniFLEX the solution for writing new user programs which interact your next high-performance system contact either directly with the network.
