This manual describes how terminals, printers, and other serial devices are connected to the HP 3000 Series 900 computer. It includes an explanation of how terminal, printer, and other serial device input/output (I/O) is controlled by the MPE/iX operating system, and presents an overview of both the hardware and software needed to accomplish communications in an asynchronous serial mode. Step-wise configuration for the HP 3000 and the Datacommunications and Terminal Subsystem (DTS) is presented in this manual. Printer and terminal type files are discussed, as well as various other topics that impact how communications take place between an asynchronous device and the computer. PAD configuration is discussed in this manual. If you are configuring system-to- system X.25 or PAD configuration networking capabilities on a HP 3000 Series 900 computer using host-based network management, use Configuring and Managing Host-Based X.25 Links instead of this manual to configure DTCs and DTC connections. This manual may still be needed for some DTS related tasks that are outside the scope of X.25 and PAD connections configuration. This manual contains information on such tasks as: the details on creating and modifying profiles in chapter 7, Additional DTC Configuration in chapter 8, and Using NMMGR in Maintenance Mode in appendix A.
NOTE MPE/iX, Multiprogramming Executive with Integrated POSIX, is the latest in a series of forward-compatible operating systems for the HP 3000 line of computers.
In HP documentation and in talking with HP 3000 users, you will encounter references to MPE XL, the direct predecessor of MPE/iX. MPE/iX is a superset of MPE XL. All programs written for MPE XL will run without change under MPE/ iX. You can continue to use MPE XL system documentation, although it may not refer to features added to the operating system to support POSIX (for example, hierarchical directories). Finally, you may encounter references to MPE V, which is the operating system for HP 3000s, not based on the PA-RISC architecture. MPE V software can be run on the PA-RISC HP 3000s (Series 900) in what is known as compatibility mode. Skills and Tasks Configuring Systems for Terminals, Printers, and Other Serial Devices will be of greatest value to the person responsible for the overall operation and reliability of an MPE/iX computer. This person is usually called the system administrator or system manager, and needs to be able to prepare devices for operation and to configure the computer to recognize asynchronous devices. This person also needs to configure the computer for either host-based network management or PC-based network management. Guide to This Manual This manual is divided into the following chapters and appendices: * Chapter 1, Introduction, introduces Asynchronous Serial Communications (ASC) and the organization of the hardware and software used by the Datacommunications and Terminal Subsystem (DTS). * Chapter 2, Before Configuring Terminal and Printer Connections, explains how to prepare to configure communications between the HP 3000 computer and serial devices, such as terminals and printers. This chapter also provides worksheets to help you in configuration. * Chapter 3, Automatic Configuration of DTCs, describes how to add and configure a new host-based managed DTC to the HP 3000 system without needing to specify detailed configuration information such as DTC cards/boards and ldevs. * Chapter 4, Dynamic Configuration and DTS Shutdown/Restart, describes how to dynamically configure DTS as well as how to shutdown and restart DTS without rebooting the HP 3000 host. Detailed DTS configuration steps are described in chapters 5 and 6. * Chapter 5, Configuring Serial Devices (for Host-Based Management), lists steps to configure terminal, printer, and other serial device connections, when your DTCs are managed by the HP 3000 computer. * Chapter 6, Configuring Serial Devices (for PC-Based Management), lists steps to configure communications between the HP 3000 computer and serial devices, when your DTCs are managed by an OpenView Windows Workstation (PC). * Chapter 7, Terminal and Printer Profiles, explains what are terminal and printer profiles, and how to create and modify your own terminal and printer profiles to suit your environment. * Chapter 8, Additional DTC Configuration, describes how to configure additional configuration parameters that are available from the DTC Configuration screen. * Chapter 9, Describing Asynchronous Devices, describes how devices are viewed by the MPE/iX operating system and how their functionality is affected by the operating system. It also explains how asynchronous serial communications (ASC) controls devices and the flow of information between the system and devices. * Appendix A, Using NMMGR in Maintenance Mode, describes NMMGR's maintenance mode interface used to manage network directory and configuration files as well as to generate job streams to update remote network directory and configuration files. A special discussion of the SUMMARYCONF command is also included * Appendix B, Migrating from Previous Releases, describes the steps to migrate network configuration files from previous MPE/iX and MPE V releases to the current release format. * Appendix C, DTC User Interface, describes how to use the interface and what commands are available. * Appendix D, Error Messages, lists error messages and causes and actions for each message. * Glossary provides definition of commonly used terms and concepts. Helpful Manuals When using Configuring Systems for Terminals, Printers, and Other Serial Devices, these manuals should be available for reference: * Configuring and Managing Host-Based X.25 Links (36939-61004).

These tasks are not covered in this manual: 1. Set up your HP 3000 and make sure it is operational. Refer to your HP 3000 installation manual. 2. Install the DTC terminal servers on your LAN and connect the serial devices to the DTC terminal servers. Refer to your DTC hardware installation guide. Configuration Overview Using New Configuration File The following steps summarize the procedure for configuring your HP 3000 systems to use DTC terminal servers if you are using a new network configuration file. For detailed information on these steps, refer to chapters 5 and 6. 1. Create your network configuration file NMCONFIG.PUB.SYS. 2. Run NMMGR.PUB.SYS. 3. Enter your HP 3000 node name, link name, and LANIC slot number. 4. Define each DTC to be connected with the HP 3000. 5. Configure each board in the DTC. 6. Validate your network configuration. (SYSGEN cross-validation is done automatically within NMMGR.) 7. Exit NMMGR. 8. Perform a DTS shutdown and restart (or reboot your HP 3000). Dynamic Configuration You can also make many DTS changes dynamically without rebooting the system or performing a DTS shutdown/restart if you already have a valid network configuration file and there were no DCC errors reported during the last system reboot. The steps below summarize the procedure for dynamically configuring DTS. Refer to chapter 4 for more information on dynamic configuration. For detailed information on the steps below, see chapters 5 and 6. 1. Run NMMGR.PUB.SYS. 2. Modify your existing DTS configuration as necessary. 3. Validate your network configuration. (SYSGEN cross-validation is done automatically within NMMGR.) 4. At the prompt seen after cross-validation is complete, select to have DTS changes take effect dynamically. 5. Exit NMMGR. 6. Complete any additional actions as appropriate (such as rebooting the DTC) for changes to become active. Automatic Configuration If you are using host-based management to manage your DTCs, you can also add and configure a new DTC automatically without needing to specify detailed configuration information such as DTC cards/boards and ldevs. This can be done either within the NMMGR utility or without running NMMGR. Refer to chapter 3.
NOTE If you are using the HP OpenView DTC Manager on the PC to manage the DTCs, you must also configure the OpenView DTC Manager. For more information, refer to Using HP OpenView DTC Manager (D2355-90001).
