HIGHLIGHTS IBM LAN Asynchronous Connection Server Version 2.0, (Server) supports: o Operation on Ethernet, the IBM Token-Ring Network, the broadband IBM PC Network, and the IBM PC Network Baseband with IBM NETBIOS or TCP/IP protocols. o 3270 protocol conversion, to IBM TCP/IP Hosts for LAN Attached workstations and fixed function Asynch devices. Workstations can utilize the Enhanced Bios Interface, Asynchronous Communications Server Interface, (ACSI) or TCP/IP protocols, in Telnet Client mode. o Access to shared modems, for LAN Attached Workstations, utilizing the Enhanced Bios Interface, Asynchronous Communications Server Interface, or TCP/IP Protocols, in Telnet Client mode. o Access to non-IBM TCP/IP Unix hosts, through the Server in line at a time character mode for NETBIOS workstations (Running EBI, ACSI, emulators), or Off-Net PC or PS/2 (R) devices. Those workstations that support Kermit, can use Kermit to perform bi-directional file transfers. o New Server management capabilities, a graphical-based configuration file generation utility, and a removable EBIOS module. o Operation of the EBI, or ACSI, the SoftLogic Solutions Carousel(t) and the IBM Workstation Connectivity Memory Management Enhancement (WCMME) Programs to allow task switching in a DOS machine. o Operation of the ACSI and EBI under Microsoft Windows 3.0 o Direct connect, leased line, and dial out, AT command set modems, at speeds up to 19.2 Kbs., using IBM Realtime Interface Co-Processor Multiport/2 (RTICM/2) adapters or two serial communication adapters, but not to exceed 34 lines total. (t) Software Carousel is a registered trademark of SoftLogic Solutions, Inc. DESCRIPTION USER PRODUCTIVITY The prior functions of the Server, utilizing NETBIOS as the LAN (Token-Ring Network, PC Network broadband and baseband) connection protocol remain. The Server continues to utilize the Disk Operating System (DOS). The following is a description of those functions: o LAN attached workstations, utilizing DOS, operating with ASCII emulation programs written to either the EBI or the ACSI, can be connected to the Server to share modems, to access direct connected ASCII hosts, or be connected through an CCITT V.24 interface to a terminal server attached to Ethernet, allowing access to an ASCII host on Ethernet. o Dial in through the Server can be made to a DOS LAN workstation operating a program written to either the EBI or the ACSI. NEW FUNCTION The connection mechanism of the IBM LAN Asynchronous Connection Server Version 2.0 has had new verbs added to the EBI that allow operation of the Server with different protocols. The Server operating code has been restructured into a Process function for control and switching, and Service functions such as the 3270 protocol conversion capability, and Facility functions. A new Facilities has been added; TCP/IP client and server mode. The switching module allows Facilities to be connected to each other directly, or through a Service function such as the 3270 Protocol Conversion function, then to other Facilities. An example would be a workstation operator using an ASCII emulator that operates with NETBIOS protocol, wishing to have a 3270 protocol conversion and then be connected to an IBM TCP/IP host. This results in a data stream alteration from ASCII to 3270, and a delivery system transformation from NETBIOS to TCP/IP. In operational terms this results in a NETBIOS Facility being switched into the 3270 Protocol Conversion function, and then out the TCP/IP Facility for delivery to an IBM TCP/IP host. Facilities which can be switched are: o Asynchronous (Communication Adapter Side) o NETBIOS o TCP/IP (Client and Server) The IBM LAN Asynchronous Connection Server Version 2.0 structural and functional enhancements allow operations as follows: o With Ethernet Adapters, the Server can operate with NETBIOS protocols on Ethernet. o The Server can operate with TCP/IP Telnet protocols, in Client or Server mode, on any supported LAN. o The Server can operate with NETBIOS and TCP/IP protocols concurrently, and allow connections from one protocol to the other. - The Server allows 32 TCP/IP sessions on the LAN concurrently, that is, 32 in or out or 16 in and 16 out. o Devices operating on Ethernet, to be directed to a Server on a Token-Ring Network through an IBM 8209 LAN Bridge or the opposite, from a Token-Ring Network to an Ethernet. - The Server can support both an Ethernet and Token-Ring Network adapter in the same unit allowing traffic to be routed from one LAN to the other by applications able to use the Server. One LAN adapter may be operating with NETBIOS and the other with TCP/IP protocols. o Through Telnet Client, line-at-a-time character mode access to IBM TCP/IP or non-IBM TCP/IP Hosts for the following: - NETBIOS DOS Workstations (Running EBI or ACSI Emulators). -- NETBIOS DOS Workstations that support Kermit can use Kermit to perform bidirectional file transfers between the workstation and the non-IBM TCP/IP hosts. - Off-net PC or PS/2 devices in ASCII Emulation mode. - Off-net fixed-function terminals. o LAN-attached workstations operating to EBI, ACSI, TCP/IP, or Fixed-Function ASCII devices, attached directly to the Server, can utilize the shared modems capability of Server. o Prompt for service requests, or offer menu selection, and password for LAN attached workstations before making a connection. o EBI and the ACSI application programs can operate in conjunction with SoftLogic Solutions Inc, Software Carousel, and IBM Workstation Connectivity Memory Management Enhancement programs to allow task switching. o The ACSI and EBI will function with applications that operate with Microsoft Windows 3.0 in Real, Standard or 386 Enhanced mode. o Operation with a removable EBIOS.COM module, which allows minimizing memory requirements when not using a LAN Emulator. It is included, along with the EBIOS.SYS driver. o ASCII to 3270 protocol conversion can be performed. This protocol conversion mechanism is the similar to the Yale ASCII IUP, and the IBM 7171 Control Unit, and includes the American Library Association (ALA) character set, and basic transparent I/O orders. - Functions supported are; full screen 3278 and 3277 type of emulation; extended datastream orders like SFE (Start Field Extended); Color field attributes, assigned through the terminal table definitions; a 64 byte character type ahead buffer; highlighted fields; word processing keys such as word-tab, word-delete, and word wrap; and user-configurable error messages. - WSQF, a command to query the display to find out what hardware features it supports. - A supplied terminal table definition utility allows the user to define unique terminal types. - Another utility to support modification of the IBM 7171 terminal x.TRM file types to the IBM LAN Asynchronous Connection Server Version 2.0 protocol conversion terminal types will be supplied. - Terminal tables have been set up to allow use of the following ASCII terminal types: - Lear Sigler Inc., ADM-31 AND 3A - Digital Equipment Corporation, VT100 (t) - Datamedia DM-1520, 1521 and 3045 - IBM 3101, (Model 1x and Model 2x, in character mode), and 316X - IBM 3101 emulation - TeleVideo TV 912, 920, and 950. - Typewriter type terminal, which supports Line Mode Telnet - Functions not supported are: -- Printers -- GDDM requiring 3279 support -- Multiple Logical Units per 3270 session -- Transparent sequences other than Write and Write/Read -- Graphics -- Programmable symbols, 3278 APL or Text mode, or character attributes (fields can have colors, but individual characters do not) -- Read modes other than standard Read Modified and Read Buffer -- Blink, reverse video, underscore o Protocol-converted 3270 data streams can be transferred by Telnet from the Server to an IBM TCP/IP host such as a System/390 (TM) or 9370 for the following: - LAN-attached workstations operating to EBI, ACSI, or Fixed-Function ASCII devices, attached directly to the Server. -- NETBIOS DOS workstations modified to operate with the EBI or ACSI can use Kermit to perform bidirectional files transfers between the workstation and the non-IBM TCP/IP hosts. - IBM or non-IBM workstations operating with TCP/IP in Line mode Telnet (without the TN3270 code).
