MANUAL REVISION HISTORY DX10 3270 Interactive Communications Software (ICS) User's Guide (2250954-9701) Original Issue ................................ 1 May 1979 Revision ..................................... 15 March 1980 Revision 1 March 1982 Revision 15 September 1983 The total number of pages in this publication is 218. The computers offered in this agreement, as well as the programs that TI has created to use with them, are tools that can help people better manage the information used in their business; but tools - including TI computers - cannot replace sound judgment nor make the manager's business decisions. Consequently, TI cannot warrant that its systems are suitable for any specific customer application. The manager must rely on judgment of what is best for his or her business. Preface The DX10 3270 Interactive Communications Software (lCS) provides a 990 family computer with the DX10 operating system to emulate the operation of a subset of the IBM .3270 Information Display System. This emulation allows an ICS-supported video terminal, or any DX10-supported sequential output device, to receive data from an IBM host application program. When an ICS display station receives the data, the operator can read, delete, or modify it, then send it back to the host application. The operator can also put the data onto a file or print a copy of it. An ICS printer station is a receive-only device. Once activated, the printer station can receive data transmitted by the host application program and either print a copy of it or write it onto a file without requiring an operator. ICS can also use a program that you design as an ICS display or printer station. This manual describes the operation of the ICS display station and the ICS printer station and provides instructions for activating and terminating ICS. Also, this document describes how a user-written program can operate as an ICS display or printer station. This manual addresses three audiences. Section 1 contains general intormatiol') concerning the scope of the ICS package. Section 2 provides background information about the IBM 3270 Information Display System and the DX10 operating system. Section 2 ',requires no technical knowledge and serves as an introduction for those users unfamiliar with either of these systems. Section 3 contains all the information required for a data entry operator to activate, operate, and terminate an ICS station. Section 4 contains information useful to both the systems operator and the systems analyst. Section 5 and the appendixes contain technical information for the systems analyst. Appendix A contains generic keyboard references. Appendix B contains explanations of the errors returned by ICS. Most errors can be corrected by the data entry operator, though some require attention by the systems operator or the systems analyst. 2250954-9701 iii Preface This manual is organized into the following sections and appendixes: Section 1 General Description - Introduces Interactive Communications Software (ICS) and its capabilities, and Programmed Station Control (PSC) and its capabilities. 2 Functional Environment - Describes the components and operational requirements, and thesupported configurations. This section also explains how the operating system treats user responses to command prompts. 3 ICS Station Operation - Describes the activation, termination, and operation of the ICS printer and video stations. 4 Functional Description - Describes the installation process, ICS line activation, configuration management utilities, and the statistics kept by ICS. 5 Programmed Station Control (PSC) - Describes PSC, its capabilities, and its operation. Appendix A Generic Keynames - Describes the generic keynames for video terminals. B ICS Messages and Codes - Describes the error messages that may be logged or displayed during operation of ICS or PSC. C ICS Hardware Requirements - Describes the memory and hardware requirements of the ICS and PSC. D ASCII/EBCDIC, EBCDIC/ASCII Translation Table - Describes the EBCDIC character set supported for an ICS station and provides the ASCII-to-EBCDIC and EBCDIC-to-ASCII code translations. E Summary of ICS Commands and Key Functions - Provides a complete list of ICS SCI commands and special key functions the ICS supports. F Binary Synchronous Communications (BSC) Procedures - Describes the protocol that ICS uses to communicate with an IBM-compatible host computer. iv 2250954-9701 Preface The following documents contain information about the DX10 operating system, the video terminals that ICS supports, and the printers that the operating system supports.
