Uniflex News UniFLEX News Technical Systems Consultants, Inc. SUMMER 1989 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 operating system. UniFLEX is a multitasking, Talk - Interactive network conversations mUltiuser, Unix-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 C 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 compiler, 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.

Hay 15, 1989 '\ RE: Tep/IP Support for GHX computers Technical Systems Consultants, Inc. is pleased to announce immediate availability of two networking packages for GMX computers running the UniFLEX Operating System. One package supports the GMX Arcnet controller, the other supports the new GMX Ethernet interf~ce. Both are based on the Tcr/lr network protocol. Once two or more GHX systcm3 ore networked with UniFLEX, the following user level applications are available: Telnet This program allows a user to login onto any system connected to the network. The result is exactly as if a direct terminal connection had been made. Ftp This is a file transfer program which allows the uscr to effortlessly send or receive files from any system cOllneded to the network. Rsh This application allows a user to execute a ~inqle sh~ll rnm~and or script on any system connected to the network. This command also allows I/O redirection and pipes between machines. Rlogin This program is similar to Telnet, bllt will aUlr)Matically login the user on the requested machine under that user's name. sandmail This application provides a very powerful electronic ~ail facility between all systems connecte~ to the network. Hail sending, receivinq, collection, and reviewing facilities are all provided. Talk Talk allows an interactive terminal link between two users anywhere on the network. This is more efficient than mail if the desired user is known to be on the system at the time. -------_.. ..-.----------------~----- "1 Providence Road. Chapel Hill. North Carolina 27514· (919) 493-1451 • TWX 510-920-0540 Our Tep/IP implementation offers two advantages over most others. The first is automatic routing capabilities. This allo~s users to communicate with systems on the network without knowing their exact location in the network, or the path from their local machine. The second advantage is speed. We have one of the fastest TCP/IP implementations available (up to three times faster than. others). There is one bonus with our implementation as well. Because of the automatic routing capability, a system can support both Ethernet and Arcnet in the same machine, allowing data from the Arcnet to reach systems on the Ethernet, and vice versa. The Tep/IP Networking Package is only available for the real-time UniFLEX Operating System. The price of the option is $400.00 when ordered with the operating system. Current users may upgrade for $450.00 and must return their original disKs. For users currently o~ning non-realtime systems, an operating system upgrade to the. realtime version, plus the Tep/IP option, is $650.00. Only systems purchased prior to May 15, 1989 are qualified for thisspeeial upgrade price.

  • Introl-C Brochure.Pdf
    INTROL-C/6809 C LANGUAGE DEVELOPMENT SYSTEM Introl-C/6809 is a powerful C language compiler system that is designed to facilitate the development of high-efficiency software for the 6809. The Introl-C package includes a C Compiler, 6809 Relocating Assembler, Linker, Loader, Library Manager, and Standard Library. It has been in the field since early 1982 and has gained widespread acceptance among users for its reliable and comprehensive support of the C language as well as its ease of use. Its ability to generate exceptionally compact, fast executing code has long distinguished the Introl-C implementation as being the most efficient high level language that is available for the 6809 and has resulted in Introl-C's widespread use in the industrial community for development of process control software. Programs developed using Introl-C are typically within 15 to 20% or less of the size and speed of programs written entirely in 6809 assembler. For the particular case of the Eratosthenes Sieve Benchmark, the p/n UC6809 resident Introl-C Compiler, for example, produces a 176 byte compiled module, a total program size of 2007 bytes, and a program execute time of 8 seconds on a 2 Mhz 6809. Code produced under lntrol-C is re-entrant, relocatable, and ROMable and may be installed on any 6809 target, including ROM-based systems. No fees or royalties of any type are imposed on object code programs developed using the compiler. Introl-C/6809 is available as resident software for 6809-based hosts running UniFlex, Flex, or 0S9. Cross-software versions of Introl-C are available for PDP-11 based hosts running UNIX (or any of the URIX look-alikes such as TNIX, VENIX, etc), PDP-11 based hosts running RSX11M, and also for IBM PC hosts running PC DOS or MDOS.
