DECserver 100 Terminal Server Operations Guide

This "DECserver 100 Terminal Server Operations Guide," published in January 1985, is designed for server managers to effectively set up, manage, monitor, and troubleshoot the DECserver 100 and its attached terminals.

The document provides a comprehensive overview of the DECserver 100's environment within a Local Area Network (LAN) using the Local Area Transport (LAT) architecture, distinguishing between local and service modes of operation and explaining its use of permanent and operational databases for configuration. It offers detailed instructions for initial and ongoing setup, including defining privileged and login passwords, configuring server characteristics (like network operation, loading/dumping, and administration), and setting terminal characteristics (such as session control, data parameters, flow control, and administration features).

The guide also covers routine management tasks, including security, managing terminal access to network services, user communication, and remote server management. A substantial section is dedicated to monitoring the server's status and network traffic using various SHOW commands. Crucially, it provides extensive troubleshooting procedures for a wide range of issues affecting all terminals (e.g., power, hardware, down-line loading), individual terminals (e.g., display problems, file transfer failures), service nodes (e.g., communication errors, group code mismatches), and Ethernet connectivity. It concludes with an alphabetical reference of all DECserver 100 commands and an appendix detailing status and error messages.
