SECTION IV
EMULATOR OPERATION
4.1 INTRODUCTION
Operation of the Emulator begins with Emulator activation. The activation defines the operating
environment. When activation is complete, communication and file exchanges may begin.
Communication and file exchanges are accomplished using the Emulator commands. The
commands may be issued by an operator in operator mode, by a command file in command file
mode, or by an intertask message queue in intenask message queue mode.
The user-supplied data in the examples in this section is italicized to distinguish user input from
Emulator input. ·
4.2 EMULATOR ACTIVATION
The Emulator may be installed with or without an Automatic Call Unit (ACU). The activation
procedure for an Emulator with an ACU includes all of the activation steps for an Emulator without
an ACU but also includes special steps concerning the ACU.
4.2.1 EMULATOR ACTIVATION WITHOUT ACU. An Emulator without an ACU is loaded and
activated from a station by entering the appropriate command, X3780 or X2780, following the
command mode indicator. ·
[ ]X2780

A<ter the command is entered, the appropriate menu of prompts is presented:
EXECUTE 2780 EM ULA TOR
COMMAND ID: ME
LOG ID: ME

or EXECUTE 3780 EMULATOR
COMMAND ID: ME
LOG ID: ME
COMM DEVICE ID:
This menu enables the user to enter the source of the command input (operator, command file,
intenask message queue), the destination of the log for the session (operator terminal, command file,
intenask message queue), and the identification of the communication line to be used. The command
source ID and the log destination ID may be any device identifier or file pathname allowed by DX JO
(including synonyms) or intenask message queue identification numbers. The command source ID
and log destination ID should not be the same unless the operation of the Emulator is in operator
mode. In operator mode, the command source and the log destination must be the operator terminal.
ME is the default for the COMMAND ID: and LOG ID: prompts. Using the default specifies that
the primary command source and the primary Jog destination for this session is the terminal
displaying the menu.
The following are examples of completed menus.
