1 Product Components and Operation This manual describes the Tandem EM3270 emulator. The emulator runs on Tandem NonStop systems to enable Tandem, IBM 3270, IBM 5250, and Fujitsu 66xx terminal users to access IBM or Fujitsu host and Tandem applications. The term “Tandem terminal” is used in this manual to refer to the 6526 terminal, the 653x family of terminals, the TS530 terminal, and personal computers capable of emulating these terminals with PCT and OV/TTE.
Emulator Features Product Components and Operation Figure 1-1. The EM3270 Emulator Tandem System EM3270 Emulator SNAX/APN SNAX/XF AS/400 IBM Host (5250) SNAX/XF IBM or Fujitsu Terminals TR3271 SNAX/CDF Tandem Terminal Access Method IBM Host (3270) EnvoyACP/XF Tandem Terminals SNAX/XF Spooler Tandem Application e.g.
Product Components and Operation Emulator Features Functions) and SNAX/CDF (Systems Network Architecture (SNA) Communications Services/Cross Domain Facility) products, when used with NonStop systems running the NonStop operating system. The EM3270 emulator can access IBM hosts using both bisynchronous and SNA interfaces. Fujitsu hosts can only be accessed using SNAX/XF. • • • • • Tandem/IBM host application switching.
System Interface Product Components and Operation System Interface Figure 1-2 shows a typical system that includes the EM3270 emulator. The emulator interfaces with IBM systems using a TR3271 process for bisynchronous host connections. The SNALU interface of SNAX/XF or SNAX/CDF is used for SNA host connections. The Tandem terminals interface with the EM3270 emulator through any Tandem access method that supports Tandem terminals.
Product Components and Operation Operational Overview Figure 1-2. The EM3270 Emulator System Interface Tandem System EnvoyACP/XF SNAX/CDF Tandem Application e.g. Pathway IBM Host Terminal Access Method EM3270 Emulator Spooler EMCOM Printer Central Operator SNAX/XF TR3271 S5091-002 Operational Overview You can start and control the EM3270 emulator in either of two ways: • Central operator control: A central operator configures and starts the EM3270 emulator.
Dual-Application Session • Product Components and Operation User control: A user can configure and start the EM3270 emulator from any Tandem, IBM, or Fujitsu terminal that has an active command interpreter. The user performs the functions otherwise performed by a central operator, in addition to the user functions of the application. In either case, the terminal emulates the IBM 3270 information display system when it accesses an IBM host.
Product Components and Operation Single-Application Session Tandem Application Requirements A Tandem application that accesses the EM3270 emulator terminal must meet the following conditions: • • • It must be a block-mode application. It must not require more than seven-page buffers. It must not require control of the BREAK key. See the bulleted item “Tandem/IBM host application switching” under “Emulator Features” earlier in this section for more information.
Bisynchronous Mode Session Product Components and Operation Bisynchronous Mode Session Logging on to an IBM application is the same regardless of whether switching to a Tandem application is permitted. In the bisynchronous mode, the IBM host application opens the terminal and starts polling under control of commands issued by the IBM central operator. If the timeout value for the terminal has not expired, you can initiate processing by pressing the CLEAR key.
Product Components and Operation Printer Session To display a selection menu that shows the available applications on a 6530 terminal, press the shifted ROLL UP key. To select an application, press the function key associated with it. Data transferred between the EM3270 emulator and the access method is in ASCII format. Note.
Log File Operations Product Components and Operation options for each printer during configuration. See the SET TIMEOUT and SET EOFTEXT command descriptions in Section 4 under “EM3270 Emulator Command Set.” When the emulator detects an end-of-file, either as a defined character string or through elapse of a specified time period during which no characters are received, it closes the current file and opens a new file. This causes the spooler to queue the file for printing.
Product Components and Operation Terminal Buffer Strategy Screen Recovery The emulator has restart and recovery capabilities that become effective in the event of terminal or system power failure. The EM3270 emulator automatically performs terminal initialization when a power-on status message (error 191) is received from a terminal device. If the SHIELD option is set to OFF, the power-on error will be passed through to Pathway, causing Pathway to perform its screen recovery.
Data-Stream Switching Method Product Components and Operation Data-Stream Switching Method In a dual-application session, the terminal user can switch from the Tandem application to the IBM application and from the IBM application to the Tandem application by pressing the SWITCH key. Alternatively, you can install a procedure that inspects a data stream to detect switching commands that automatically switch applications. This datastream switching method is described in Appendix G.
Product Components and Operation PCT Color Mapping In PCT versions G40 and later, several enhancements were implemented that enable EM3270 to overcome most of the architecture differences between the 3270 and the 6530. Tandem terminals delete trailing spaces in fields; that is, these terminals consider a trailing space to be identical to a null character. The EM3270 emulator defines a SPACE function key for inserting trailing spaces.
The EMCOM Interpreter Product Components and Operation The EMCOM Interpreter The EMCOM interpreter processes emulator commands and directs the operation of the emulator according to those commands. Both the central operator and the terminal user can type in commands. EMCOM can also accept commands from a file. Type in the following command to execute EMCOM: EMCOM [/run-parameter [, run-parameter].../] [process-name] [; command...

2 Keyboard Mapping This section describes the keyboard translations for Tandem, IBM, and Fujitsu terminals that occur during an emulator session. It also describes the control keys that you can use during Tandem applications and host accesses. It is addressed to the terminal user.
Tandem Terminal Keyboard Translations Keyboard Mapping Table 2-1 shows function-key mapping for Tandem terminals and emulators while in session with an IBM 3270 or Fujitsu 6680 host: Table 2-1.
Keyboard Mapping Tandem Terminal Keyboard Translations Table 2-2 shows function-key mapping for Tandem terminals and emulators while in session with an IBM 5250 host, such as the IBM AS/400: Table 2-2.
IBM 3270 Emulation Mode Keyboard Mapping IBM 3270 Emulation Mode When you are accessing the IBM host (single- and dual-application sessions), the function keys on the top row of the Tandem keyboard (F1 through F16) generate most of the control-key functions available on an IBM 3270 information display system. These include: • • • • • • • • • • • • • • • • • • • 2- 4 ATTN: Indicates the attention key, for SNA mode only. BACKSPACE: Requests a record backspace operation.
Keyboard Mapping IBM Emulator Template and Keycap Label Installation In addition to the IBM key functions, the Tandem terminal generates other control codes, including: • • • • • • ALIAS and ALIASMODE: Enables you to customize the host switch screen procedure. Refer to Section 4, “EM3270 Emulator Command Set,” for more information. HOST: Initiates a switch to a different application program in the IBM or Fujitsu host.
Tandem Application Session Keyboard Mapping Tandem Application Session When a switch is made to the Tandem application in a dual-application session, only the ROLL UP, NEXT PAGE, shifted NEXT PAGE, and shifted PREV PAGE key codes are intercepted by the emulator to generate the PRINT, SWITCH, STOP, and RCOVR commands, respectively. All other function keys are passed through to the application without modification by the emulator program.
3 Basic and Advanced Sessions With EM3270 This section describes the operating procedures associated with configuring and running the EM3270 emulator program. It describes a basic interactive stand-alone session in which the emulator process is configured and started from the home terminal. It also describes the case in which the emulator is configured and brought up interactively from a central operator terminal to run a session on a second terminal.
Preliminary Activities Basic and Advanced Sessions With EM3270 Preliminary Activities Before you run EMCOM to initialize the EM3270 emulator, and when using TR3271, SNAX/CDF, SNAX/APN, or SNAX/XF, you need to configure and start the subdevices for the access method using SCF. Refer to the SCF Reference Manual for SNAX/XF and the SNAX/CDF Configuration and Control Manual for details. Another optional step includes defining a log file to store text-format messages generated during the session.
Basic and Advanced Sessions With EM3270 Example Single-Application Session File-Name Expansion Most EMCOM commands involve a file name that is a symbolic identifier for a unique disk file.

EM3270 Emulator Command Set VOLUME Command TRACE Command The TRACE command starts and stops the EM3270 diagnostic trace. This command is useful to capture a problem sequence or failure that can be submitted to Tandem to facilitate problem resolution. Tracing is performed on an individual task basis. One or more tasks can be traced at the same time. TRACE { file-name | task-number } [,{ ON | OFF } ] file-name specifies a fully qualified network terminal file name.
X Command EM3270 Emulator Command Set X Command The X command causes EMCOM to temporarily suspend processing and start a process using the object module progname. If progname is not fully qualified with volume and subvolume, EMCOM first attempts to execute progname in the current volume and subvolume. If that file does not exist, EMCOM then attempts to execute $SYSTEM.SYSTEM.progname. This command is valid only in interactive mode. EMCOM resumes processing when the progname program terminates.
5 Problem Solving This section provides guidelines for solving problems that may occur in the EM3270 emulator environment. Solving Common Problems In general, most problems you might encounter during initial system configuration can be traced back to an SCF error or the SYSGEN process. Before continuing with the troubleshooting procedures, ask the computer system manager to recheck the SCF procedures.
Writing a Trace File Problem Solving The TRACE command closes the trace file and displays the following message: STATUS *1126* TRACE STOPPED For example, a session trace for terminal $TERM1 can be captured using the following sequence: }SET TRACFILE $S.#EMTRACE }TRACE $TERM1,ON . . . }TRACE $TERM1,OFF }EXIT To view the trace file, use FUP COPY (refer to the File Utility Program (FUP) Reference Manual).

C Transliteration Option This appendix describes the procedure for performing ASCII-to-ASCII conversions when using a character set other than English. Languages other than English have a problem with byte-synchronous controller EBCDIC-to-ASCII and ASCII-to-EBCDIC translations. To overcome this problem, EM3270 is equipped with an option that permits ASCII-to-ASCII translation on inbound and outbound data blocks in the IBM host session. You must provide two conversion tables for this purpose.

E Color-Mapping and Function-Key Mapping This appendix describes the EM3270 emulator PC6530 (PCT) color support and provides three user-replaceable procedures that control color mapping for 3270 base and extended color support. It also summarizes the function-key mapping operations that take place when the emulator is running and describes the procedures for replacing the standard set of function-key mappings with a customized set.
PCT Color Mapping Color-Mapping and Function-Key Mapping Unprotected Normal (dim) video Green Unprotected Bright video Protected Normal (dim) video Blue Protected Bright video Red White The second type is extended color mapping and is implemented by the Start Field Extended Order (SFE) as follows: SFE, # of attribute pairs, attribute type, attribute value ... # of attribute pairs specifies the number of attribute type-value pairs that follows.
Color-Mapping and Function-Key Mapping PCT Color Mapping The Modify Field Order (MF) uses the same subfield structure as SFE. The subfields are used to update the characteristics of an already existing field rather than create a new field as does SFE. PCT Color Support PCT version C00 implemented 32-color support using the 5 bits of the video attribute byte of the SF and SFE 6530 field definition commands. The format of the video attribute byte is described in Figure E-1. Figure E-1.
PCT Color Mapping Color-Mapping and Function-Key Mapping Figure E-2. Base Color-Support Mapping Procedure INT PROC user^base^color^mapping (attribute, video^attr); INTattribute, video^attr; BEGIN LITERAL dim blink reverse blank underline normal ! ! ! ! Contains the IBM attribute byte. Contains the 6530 video attribute. The result of the PROC is an updated video attribute.

Contains the 6530 video attribute. Contains the 6530 data attribute. The result of the PROC is an updated video attribute. BEGIN INT hilite := hilite^color.< 0: 7> INT color := hilite^color.
PCT Color Mapping Color-Mapping and Function-Key Mapping User Decode Color-Support Mapping The support of the MF also requires that all of the information used to initially perform color mapping for a field be available to be updated by the MF subfields and then be color mapped by the user^ext^color^mapping procedure. The EM3270 emulator only stores the result of the color-mapping process (for example, the data and video attributes).
Color-Mapping and Function-Key Mapping Alternate Function-Key Mapping EM3270 Emulator Function-Key Mapping This subsection describes the function-key mapping when the emulator is running and describes the procedures for replacing the standard function-key mapping set with a customized set. Table E-2 lists the default mapping performed by the emulator. Table E-2.
Alternate Function-Key Mapping Color-Mapping and Function-Key Mapping To specify different mappings of the function keys, reorder the numbers in the INT declaration that initializes array f^to^aid. The values placed in the array correspond to 3270 functions. The sequence of these values corresponds to the sequence of the function keys. When you rearrange the numbers in the array, you map the function keys to different 3270 functions. To disable a function key, replace the value shown with a -1.
Color-Mapping and Function-Key Mapping Alternate Function-Key Mapping Figure E-5.
Alternate Function-Key Mapping Color-Mapping and Function-Key Mapping Declarations for the function-key mapping procedure for a Tandem terminal emulator (for example, PCT.EXE) are shown in Figure E-6. Note. The EM3270 emulator uses the READ TERMINAL STATUS COMMAND (ESC ^) to determine which user mapping procedure to use. If the device returns a terminal ID of “F”, the user^function^key^mapping^tnt procedure is used. Otherwise, the user^function^key^mapping procedure is used. Figure E-6.

J Event Management Service This appendix describes the Event Management Service (EMS) events generated by the EM3270 subsystem. This section describes: • • • The overall strategy for EM3270 subsystem events. The tokens used in EM3270 subsystem events. The event messages reported by the EM3270 subsystem. Event Reporting Strategy The overall goal of EM3270 event reporting is to allow the EM3270 subsystem administrator to monitor and control the operation of the subsystem.
Error Lists Event Management Service event is not considered critical. EM3270 designates an event as critical in the following cases: • • • • There was a potential or actual loss of data. There has been a loss of a major subsystem function. There has been a loss of fault-tolerance capability. An unrecoverable internal error occurs. Error Lists Some of the events report NonStop Kernel operating system or file-system errors.
Event Management Service Standard EMS Tokens Standard EMS Tokens This section describes the EMS-defined tokens that will exist in all event messages generated by the EM3270 subsystem. ZEMS-TKN-CONSOLE-PRINT specifies the value ZSPI-VAL-TRUE if the message should be distributed by $Z0 for compatibility with the old-style operator messages, and ZSPI-VAL-FALSE otherwise. ZEMS-TKN-CPU indicates the CPU number from which the event was generated.
NonStop Kernel Tokens Event Management Service ZEMS-TKN-SUBJECT-MARK indirectly indicates the subject token which is ZCOM-TKN-SUBJ-PROC. ZEMS-TKN-SYSTEM contains the system number. ZEMS-TKN-USERID contains the user ID of the originator process. NonStop Kernel Tokens This section describes the NonStop Kernel tokens that may exist in event messages generated by the EM3270 subsystem. ZGRD-TKN-BINDTIMESTAMP contains the object file’s BIND (session-initiation request or response) timestamp.
Event Management Service Data Communications Tokens ZGRD-TKN-PROCESSNAME identifies the process pair name. ZGRD-TKN-SREGISTER contains the S-register at the time. ZGRD-TKN-STACKENV contains the stackmarker ENV. ZGRD-TKN-SWAPFILE identifies the SWAP file. File-System Tokens This section describes the file system tokens that may exist in event messages generated by the EM3270 subsystem. ZFIL-TKN-FILENAME identifies the file name on which an error occurred.
EM3270 Tokens Event Management Service ZCMK-TKN-CPU contains the CPU number of the process involved in the event. ZCMK-TKN-CMD-CODE identifies the command about which the event is being noted. ZCMK-TKN-FILE-ROLE indicates the role played by the file involved in the event. ZCMK-TKN-FNUM identifies which file was involved in an error. The value represents the file number used by the requesting program, not the file number used within the EM3270 subsystem.
