Subsequent executions of the Emulator will display the menu including the previous response to the
COMM DEVICE ID: prompt. If this response is correct, use a carriage return to avoid rekeying.
If an error is made in response to one of the prompts, the system responds with one of the following
messages:
COMMAND DEVICE NOT AVAILABLE
LOG DEVICE NOT AVAILABLE
INVALID PARAMETERS
If the responses are all correct, the Emulator is executed and responds with a header of the form:
DXlO/XXXX V.R.U. VY.DOD
where
XXXX is 2780 or 3780, whichever is being executed,
V is the version number,
R is the release number,
U is the update level,
YY is the last two nurrtbers of the year of the Emulator release, and
DOD is the Julian date within the year of the Emulator release.
This is followed by the Emulator COMMAND: prompt.
4.l.l EMULATOR ACTIVATION WITH ACU.
An Emulator with an ACU is loaded and
activated from a station by entering the appropriate command X3780A or X2780A following the
command mode indicator.
[ ]X2780A
or [ ]X3780A
After the command is entered, the appropriate menu of prompts is presented:
EXECUTE 2780 EMULATOR WITH ACU or
COMMAND ID: ME
LOG ID: ME
COMM DEVICE ID:
ACU CRU ADDR:
EXECUTE 3780 EMULATOR WITH ACU
COMMAND ID: ME
LOG ID: ME
COMM DEVICE ID:
ACU CRU ADDR:
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), the identification of the communication line to be used, and the automatic
call unit CRU address. The command source ID and the log destination ID may be any device
identifier or file pathname allowed by DXIO (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 this default specifies that the primary command source and the log
destination will be the terminal displaying this menu. The ACU CRO address is a hexadecimal
number giving the location of the ACU on the CR U bus. If the user's system has only one
communication line, the procedure may be edited to automatically pass the CRU address to the task
