Organization

This manual is divided into the following Chapters and Appendixes:

Chapter 1 “Introducing SNA IMF” gives an overview of SNA IMF, its capabilities, and its operating environment, including software and hardware requirements.

Chapter 2 “Configuring Pass Thru” explains how to create the file PTCONFIG.PUB.SYS, which SNA IMF Pass Thru uses to determine the functions of your rolling softkeys and various other Pass Thru options.

Chapter 3 “Starting Pass Thru” explains how to start up SNA IMF Pass Thru for terminals and printers.

Chapter 4 “Stopping Pass Thru” explains how to terminate a Pass Thru session for a terminal or a printer.

Chapter 5 “Using Terminals with Pass Thru” describes the Pass Thru characteristics and features of HP terminals and how they compare with IBM terminals. It also describes how to set terminal transmission speeds, how to display session status information on your terminal, and how to access the MPE command interpreter from a Pass Thru session.

Chapter 6 “Using Printers with Pass Thru” explains how to use Pass Thru to emulate an LU.T1 or LU.T3 printer.

Chapter 7 “Pass Thru Over X.25”explains how to use Pass Thru to communicate with the remote host from a PAD device in an X.25 network.

Appendix A “Pass Thru Messages” lists the messages that Pass Thru can generate, the probable causes of the messages, and the actions you can take to resolve problems.

Appendix B “SNA Character String (SCS) Support” describes SCS control codes and support for LU.T1 printers.

Appendix C “Pass Thru Terminal and Printer Specifications” lists the HP terminals and printers that you can use with Pass Thru.

Appendix D “Sample PTCONFIG File” provides a sample Pass Thru configuration file for you to use as a guideline when you create your own PTCONFIG file.

Appendix E “3270 Bit Assignment and Character Translation Tables” provides bit assignments for 3270 field attribute characters and write control characters (WCC); lists the Attention ID codes generated by SNA IMF; gives the command codes for the IBM cluster controller; supplies 3270 buffer control orders; and discusses character sets, character translation tables, and Native Language Support.

Appendix F “Differences Between IMF/3000 and SNA IMF/V” compares the similarities and differences between the two IMF products. This appendix is useful if you are migrating from the IMF/3000 product to SNA IMF/V.

Appendix G “HP and IBM Differences in DBCS Implementation” describes how HP and IBM differ in their implementation of Asian Double-Byte Character Sets (DBCS).
