VT102 User Guide| + | Contents | +Chapter 1 | +
The VT102 video terminal is an input and output device of a computer. +The terminal uses a keyboard and video screen to communicate with a +computer.
+As an input device, the terminal transmits keyboard entries to the computer.
+As an output device, the terminal displays characters received from the +computer on the screen (using advanced video features) or prints them +on an optional printer. The optional printer connects to a serial printer interface +included with the terminal. The printer provides printed copy without +the need for a separate communication line and interface to the computer.
+This user guide describes general operating information, interface information, +control function descriptions, and specific installation and checkout +procedures. The main audiences for this guide are the operator, application +programmer, and terminal installer. However, the operator should +use this guide only as a reference when operating the terminal. The +primary reference for the operator is the document that describes how to +use the application software. The application software (program) determines +how the computer and terminal operate.
+The information in this user guide is divided by function. This allows you to +reference a specific chapter when you want to perform a given function. +Chapters are arranged by frequency of use. For example, operating information +is frequently used, so it appears in Chapter 1; however, installation +is usually performed only once, so it appears in Chapter 7.
+Chapter 1 provides a general description of terminal controls and indicators. +It also describes general operating procedures. Detailed operating +procedures depend on the computer and software.
+Chapter 2 describes how to print with the optional serial printer. It also +describes the keyboard procedures that select printing operations.
+Chapter 3 describes each SET-UP feature in detail and how to select +each feature. Many SET-UP features change the way the terminal +communicates with the computer. Chapter 6 provides detailed information on +communication and related SET-UP features.
+Chapter 4 shows the characters transmitted by each terminal key.
+Chapter 5 describes how the terminal processes received characters. It +also describes the use of control functions. Control functions control the +display, processing, and transmission, of characters received by the terminal. +The application programmer uses this chapter when creating applications +software for the terminal.
+Chapter 6 describes how the terminal communicates with the computer +and printer. It includes descriptions of the communication features.
+Chapter 7 describes unpacking and installation procedures, including environmental +conditions to consider before installation. The chapter also +describes step-by-step procedures to turn on (power up) and check out +(verify the proper operation of) the terminal.
+Chapter 8 describes the 20 mA current loop interface option, including installation +and checkout procedures.
+Chapter 9 describes all maintenance and troubleshooting procedures to +use before requesting service. The troubleshooting information covers the +terminal's self-tests.
+Chapter 10 lists each accessory and supply, including part number and +ordering information.
+Appendix A provides VT102 specifications.
+Appendix B summarizes the SET-UP feature displays.
+Appendix C summarizes the character codes and control functions used +to program the terminal.
+Appendix D describes the ANSI code extension techniques used to create +escape and control sequences.
+Appendix E describes the differences between the VT102 and VT100 terminals.
+Warnings, Cautions, and Notes
+Warnings, cautions, and notes have specific meanings in this user guide.
+Warnings contain information to prevent personal injury. Cautions contain
+information to prevent damage to the terminal. Notes contain important
+general information.
