VT132

This user guide provides comprehensive information on the VT132 editing terminal, covering its operation, features, installation, maintenance, troubleshooting, and programming. The VT132 functions as a high-performance video terminal, capable of both block mode and interactive operations, and is designed to be easily tailored to specific applications.

The document is structured into several parts:

1. Controls and Indicators: Details the various keys on the detached keyboard (standard, special function, numeric keypad, SET-UP, and edit mode keys), keyboard indicators (e.g., ON LINE, LOCAL, KBD LOCKED, INSERT, EDIT), monitor controls (power switches), and audible indicators (short tones, long tones, series of long tones for nonvolatile memory errors).
2. SET-UP Mode: Explains how to customize the terminal's built-in features, which are stored in nonvolatile memory (NVR). This includes settings for tab stops, scrolling, auto-repeat, XON/XOFF, protected fields, display parameters (characters per line, cursor type), edit key behavior, erasure mode, interlace, keyclick tone, line/local mode, local echo, margin bell, new line, parity, power line frequency, print options, receive/transmit speeds, screen background/brightness, space compression, wraparound, and character set selection. It describes three SET-UP screens (A, B, C) for different feature categories, and outlines procedures for setting the answerback message, parity, and invoking default conditions.
3. Editing: Covers basic editing functions such as adding, deleting, and inserting lines and characters, and correcting typing errors. It emphasizes the terminal's capability to display and protect data entry formats and transmit data in blocks to optimize host computer efficiency and ensure data accuracy.
4. Self-Testing: Describes the terminal's built-in self-test mode, which automatically or on command checks components like screen memory (RAM), nonvolatile memory (NVR), program memory (ROM), and the keyboard. It categorizes errors as fatal (halting operation) or nonfatal (forcing LOCAL mode and displaying an error character), listing various nonfatal error types.
5. Troubleshooting: Offers a problem checklist with symptoms and suggested corrective actions for common issues, including power problems, unresponsive keyboards, garbled characters, or nonvolatile memory difficulties.

Additionally, the guide includes chapters on Installation, Interface Information, and Specifications, detailing physical setup, user maintenance, EIA RS232-C and 20 mA Current Loop interfaces, and comprehensive technical specifications. A Programmer Information chapter provides in-depth details on keyboard-generated codes, terminal control characters, ANSI/VT52 mode control sequences, full duplex protocol, XON/XOFF synchronization, and block transmission modes. Finally, a section on VT132 Options outlines available accessories and their installation. Appendices contain ANSI definitions, an ASCII code chart, and fill character requirements.
