STATEMENT (Applies only to those machines used
in the U.S.)
Warning: This equipment generates, uses, and can radiate radio
frequency energy and
if not installed and used in accordance with the

Introduction
Chapter 1. Introducing the U.S. English Cartridge to
Emulate IBM and DEC Terminals
The "U.S. English cartridge to emulate IBM and DEC terminals" supports:
• The EIA RS-422A interface (available in all modes that this cartridge
supports)
• Emulation mode (mode to emulate the DEC VT220)
• SYSTEM ATTACH mode
• The IBM 3101 emulation mode
• The IBM 3151 native mode
• Ten ASCII terminals' emulation modes.
This guide explains the:
• Emulation mode (mode to emulate the DEC VT220)
• SYSTEM ATTACH mode.
Chapter 1. Introducing the U.S. English Cartridge to Emulate IBM and DEC Terminals 1-1

Introduction
Changing the Machine Mode
The machine mode can be changed in the following order in the setup menu.

Machine modes are classified into five groups:
• IBM 3151
• IBM 3101

t
VT100
t
VT100 CONTROL 7
t
VT200 CONTROL 8
t

TVI925E/925
• Ten ASCII terminals (ADM 3A, ADM 5, ADDS VP A2,HZI500,
TVI910 + /910, TVI925E/925, and TVI920/912)
• DEC VT220 (VT220 CONTROL 7/8, VT100, and VT52)
• SYSTEM ATTACH.
When the machine mode is changed to a new machine mode in a different group
(from VT52 to SYSTEM ATTACH, SYSTEM ATTACH to IBM 3151, IBM
3151 to IBM 3101, IBM 3101 to ADM 3A, or TVI920/912 to VT200 CONTROL
8 in case of using the setup menu), a power-on reset (except the checking of the
internal circuits) is performed. When the machine mode group is changed in the
setup menu, the setup menu for the new machine mode is then displayed.
Note: The machine mode can also be changed by using the Set Control 1
command (see "Set/Read Control 1 Commands/Response" on page 5-12).
1-2 User's Guide for the Cartridge to Emulate IBM and DEC Terminals

Introduction
When SYSTEM ATTACH, IBM 3151, or IBM 3101 is selected for the machine
mode in the setup menu, the new machine mode is immediately saved. That'is, if
you select SYSTEM ATTACH and exit setup menu without performing the Save
function, the machine
mode is set to SYSTEM ATTACH. The machine mode
'will also be set to SYSTEM ATTACH the next time power is turned on.
On the other hand, when one of the ten ASCII terminals or the DEC VT220 is
selected for the machine
mode in the setup menu, the new machine mode is not
saved at this point. That is, if you select VT100 and exit setup menu without
performing the Save function, the machine mode is set to VT100. However, the
machine
mode will not be set to VT100 the next time power is turned on.
Instead,
the latest saved machine mode for the DEC VT220 machine group will
be set.
You must perform the Save function to save the machine mode in this
case.
When you power-on the display station the first time with the cartridge inserted,
the machine
mode is ~t to VT200 Control 7.
• Machine Mode Switch Key
•
For the customers who use both IBM and DEC systems, this cartridge provides
the
support for a Machine Mode Switch function that allows you to switch the
machine
mode from DEC (VT52, VT100, VT200 CONTROL 7, or VT200
CONTROL 8) to IBM (IBM 3151, IBM 3101, or SYSTEM ATTACH) and vice
versa.
The Machine Mode Switch function is performed when the Send key is
pressed while holding
down the etrl and Shi/{ keys (hereinafter referred to as
Machine Mode Switch key). See Figure 1-3 pn page 1-10 for the location of the
Machine
Mode Switch key.
To use the Machine Mode Switch key, the following setup is peeded:
1. Select the machine mode and define the setup values for DEC (VT52, VT100,
VT200
CONTROL 7, or VT200 CONTROL 8). (See "Step 12A. Defining
Setup Values (emulation)" on page 2-26 for more information.)
2. Select the machine
mode and define the setup values for IBM (IBM 3151,
IBM 3101, or SYSTEM ATTACH). (See "Step 12B. Defining Setup Values
(IBM
Mode)" on page 2-29 for more information.)
Chapter
1. Introducing the U.S. English Cartridge to Emulate IBM and DEC Terminals 1-3

Introduction
Note: When you change the setup values after installation it is recommended
that you fIrst set the machine mode to the one whose vq.iues you want to change;
enter the setup menu
and change the values. That is, if the current machine mode (" '\
is IBM and you want to change the setup values for DEC, fIrst change the mode ~J
from-IBM to DEC by using the Machine Mode,Switch key; enter the setup menu.
If you enter the setup menu in IBM mode and change the setup values for DEC,
the machine mode changes as described
in "Changing the Machine Mode" on
page 1-2 and IBM 3101 will become the new IBM mode when exiting the setup
menu.
Changing the Mode between IBM and DEC
In daily operation, you can switch the machine mode, for example, from
SYSTEM ATTACH to VT100 CONTROL 7 and vice versa, using the Machine
Mode Switch key as follows:
1. Sign off the current session.
2. Press the Send key while holding down the Ctrl and Shift keys (Machine
Mode Switch key).
3. Sign on the new session.
Warning: Do not press the Machine Mode Switch key without
first terminating the current session, otherwise the current session
will be suspended and will
not operate correctly. If pressed by
mistake, press the Machine Mode Switch key again and sign off the
current session to clear the suspended state.

Introduction
Describing the
Mode to Emulate the DEC VT220
Four machine modes are available for the mode to emulate the DEC VT220:
• VT200, 7-bit controls
• VT200, 8-bit controls
• VT100
• VT52.
In most instances, you can run the same application programs that were running
the DEC VT220. However, the 3151.uses a different kind
of connector for the
main and auxiliary ports than the DEC VT220. Therefore, a cable
is necessary to
connect the
3151 to a host system or a printer. These cables should be readily
available from a cable vendor. Chapter
8, "Installation Planning" in IBM 3151
ASCII Display Station-Reference Manual provides information on the main and
auxiliary ports.
This section describes the DEC VT220 functions that are different
or not
supported when operating in emulation mode. It also describes the additional
functions and commands/response. Other DEC VT220 functions work as they
normally do in the DEC VT220.
Chapter 1. Introducing the U.S. English Cartridge to Emulate IBM and DEC Terminals 1-5

Introduction
Functions Supported Differently in Emulation Mode
The following figure shows which emulated DEC VT220 functions are different (~'\
and how they are different. \,,~
DEC VT220 Function Difference in Emulation Mode

or test mode is started
by pressing the Do key (when the
key cap is changed; otherwise the
Hold key) while holding down both
the Ctrl key and the Shift key.
Keyboard layout Key caps are provided
to emulate
the
DEC VT220 keyboard. You
should change the key caps during
setup procedures. Figure 1-2 shows
a keyboard layout
to emulate the
DEC VT220 after key caps have
been changed.

Chapter 1. Introducing the U.S. English Cartridge to Emulate IBM and DEC Terminals 1-7

Introduction
Functions Not Supported in Emulation Mode
The following functions are not supported in emulation mode:
• Changeable power supply voltage
• Keyclick
• 20 mA current loop communication interface
• Speed indicator (pin 12) and speed select (pin 23) on the main port connector
(EIA RS-232C interface)
• Video signal output port
• Data/Talk key
An integrated modem cannot
be attached.
• Selection of the receive line speed
The receive line speed depends on the transmit line speed,
that is, the latter is
selectable but the former is
not selectable, and a selected transmit line speed is
applied to the receive line speed.
Additional Functions in Emulation Mode
The 3151 provides the following additional functions:
• EIA RS-422A interface for the main port
• 25 lines of 80 characters and 25 lines of 132 characters screen support
You can select a screen format by the setup menu or by a CSI (Control
Sequence Introducer) sequence.
