 About Emulator Windows


How To Use the Emulator

The emulator has many operating features.  By using just a few, you can

•	Create a session on a host computer.  When you connect to a host computer and create a session, you can use the software applications on the host.

•	Create additional sessions on one host or more than one host computer.  If you have many sessions open, you can access multiple host applications at the same time.  For example, you could open one session to access a database, another for text editing, a third to read electronic mail, and another to complete business forms.

•	Create additional sessions using the multiple sessions protocol.  You can create multiple sessions from the host computer or the terminal server.

•	Create additional sessions using the autologin script.  This feature enables you to automate your login procedure on any host computer.

•	Use the familiar windows interface.  The windows conventions provide an easy way to use the emulator to do your work.

•	Customize each session for your work convenience.  For example, you can customize the session window, color settings, keyboard, text editing, and so on.

•	Use the editing feature to copy and paste text between sessions.

•	Use the PC keyboard like a VT keyboard, if you are use to the VT keyboard layout.

•	Start the emulator from an icon.  Use the Configuration Manager window or the Application Manager.


About Emulator Windows

The emulator provides four window types for you to use all its features.

•	Session window to create and maintain a session on a host computer.

•	Session List window to create and maintain setup data (customizations) for groups of related sessions.

•	Datascope window to troubleshoot communications between the emulator and the host computer.

•	No Open Sessions window to access the emulator menu bar when all sessions are closed.

Each window includes new commands specific to that window and commands common to the session window.  These commands enable you to use the features of the emulator, such as creating sessions, setting up the terminal emulator features, like color, printing, and closing windows.

To make full use of the windows interface, you should be familiar with windows conventions, such as using the mouse.  If you are not familiar with these conventions, refer to the Windows documentation.


Get Started

When you start the emulator for the first time, it

•	Opens a session window.  The session window contains emulator commands to create an active session on a host computer.

•	Opens a Session list window behind the session window.  The session list contains the title of the open session window.   You can use the factory default settings or reconfigure it if you have a different computing environment.

•	Puts an X across the session window.  The X indicates that the emulator is not yet connected to a host computer but is ready for you to create a session.

•	Enables factory default settings to start the emulator.  You can change the settings as needed.

	To create a session quickly without changing settings
1.	Press the Return key.   The default is for the emulator to establish serial communication through COM1 to the host computer at 9600 baud.  Most host computers communicate successfully with terminal emulators at 9600 baud.
2.	Log in to your host computer as you normally do. If you do not get a log in prompt, it probably means the Connection method is incorrect.  Go to the next procedure, To change settings and create a session.
	To change settings and create a session
1.	From the Options menu, select Communication Setup.
2.	Select the appropriate Connection method.
	To connect through... a serial port (9-pin or 25-pin connector)	Then... 1. Enter the Host name (optional). 2. Match the Port selection with the port used on the back of your system. 3. Select a Baud rate that is compatible with the host computer. 4. Select OK.
	Winsock Telnet	1. Enter the Host name. 2. Select OK.
3.	Log in to your host computer as you normally do.


Create Additional Sessions

After you have created a session on a host computer, you can create another session in the following ways:

•	Create another session quickly with the same settings as the current session.

•	Create another session with different settings from the current session.

•	Create additional sessions using the multiple session protocol.

•	Create additional sessions using Autologin Setup.

 Create Another Session Quickly

The quickest way to create another session is to use the same settings as the current session.

	To create another session quickly
1.	From the File menu, select New Session Quickly.
2.	Log in to your system as you normally do. If the emulator fails to create a new session, you need to use the multiple session protocol.  Refer to Create Additional Sessions Using the Multiple Sessions Protocol or Create Additional Sessions Using Autologin Setup.


Create Another Session with Different Settings

	To create a session with different settings from the current session
1.	From the File menu, select New Session.
2.	Select the appropriate Connection method.
	To connect through... a serial port (9-pin or 25-pin connector)	Then... 1. Enter the Host name (optional). 2. Match the Port selection with the port used on the back of your system. 3. Select a Baud rate that is compatible with the host computer. 4. Select OK.
	Winsock Telnet	1. Enter the Host name. 2. Select OK.
3.	Log in to your system as you normally do. If you do not get a log in prompt, it probably means the Connection method is incorrect.  Choose another Connection method, or contact your system manager.
4.	From the File menu, select Save. Choosing Save saves the session settings to a settings file, which enables you to log in to the same host in the same way.


Create Additional Sessions Using the Multiple Sessions Protocol

Multiple sessions defines the emulator's ability to support many sessions at the same time over one serial communication line or port by using the Terminal Device/Session Management Protocol (TD/SMP) from Digital Equipment Corporation.  The emulator supports multiple sessions with TD/SMP on one end of the communication line.  On the other end of the communication line, the host computer supports the protocol's capability with SSU, and most terminal server's from Digital Equipment Corporation support multiple sessions with TD/SMP.

The emulator supports up to 10 sessions, as does the host computer, but the terminal servers can support only eight sessions total.  The servers have a default limit of four sessions per terminal, but the system manager can increase it to eight.

Using Multiple Session Capability on the Host Computer

To enable the multiple session capability on the host computer, the system manager must install SSU on the host operating system, VMS or UNIX.  Then, the system manager or user needs to add an enabling command.

 To enable SSU on the host computer

•	On a UNIX system, the system manager must add the following command to the SYS$MANAGER:SYSLOGIN.COM file:

$  SSU  :==  $SSU

•	On a VMS system only, the system manager can add the following command to the SYS$MANAGER:SYSLOGIN.COM file or the user can add the command to the LOGIN.COM file:

$  SSU  :==  $SSU

While you are logged in to your host computer, you can initiate SSU by typing SSU ENABLE at the system prompt.  If SSU ENABLE does not work, type SSU.


Using Multiple Session Capability on the Terminal Server

The following terminal servers have the multiple session protocol (TD/SMP) installed: DECservers 90TL, 90M, 200 and higher.

 To enable multiple sessions on the terminal server

1.	Type the following commands at the Local> prompt before you log in to the host computer:

Local>  SET PORT FLOW XON

Local>  SET PORT MULTI ENABLE

2.	From the File menu, select New Session Quickly or New Session to connect to the host computer.


Create Additional Sessions Using Autologin Setup

The default for Autologin Setup is for the emulator to prompt you for the required information.  Therefore, unless you have unique host computer, modem, or terminal server parameters, choose OK in all three dialog boxes and the emulator will prompt you for your setup information.  For those who need to enter specific information, use the following procedure.

	To create additional sessions using Autologin Setup
1.	From the Options menu, select Autologin Setup.  Answer all dialogs until the Autologin (1 of 3): System Login Setup dialog box appears.
2.	Enter the information that pertains to your configuration and select OK. a. For a host connection, enter a host name, username, and user password. b. For a terminal server connection, enter a server password, if needed, and a server username. Note:  When you enter your password, the emulator stores your password in the .vtc (text) file.  The .vtc file resides in a directory that you specify.
3.	In Autologin (2 of 3), you are prompted to enter modem information. a. If you are not connecting through a modem, select OK without entering any information. b. If you are connecting through a modem, enter the required modem and Tymenet information and select OK.
4.	In Autologin (3 of 3), enter the required information for the server or the host.  Use only one connection device, then select OK. • If your host system has SSU installed, and you want to use SSU to create multiple sessions, enter MCR SSU ENABLE. • If you are connecting to the host system through a terminal server from Digital Equipment Corporation, that supports a multiple session protocol, enter SET MULTI ENABLE.
5.	After exiting the Autologin (3 of 3): Server and Host Commands dialog box, create a new session using the autologin script. • To create an autologin session quickly with the same settings as the previous session, refer to  Create Another Session Quickly. • To create an autologin session with different settings than the previous session, refer to Create Another Session with Different Settings.

Rendition	Allows you to select one or more of bold, underline, blink, and reverse image, or none at all.  For example, you can • Exchange the meaning of bold and reverse. • Define SGR 2, 3, or 6 to mean bold or underline. • Change the foreground and background colors.
Foreground	Defines the color for the text in the display area foreground.
Background	Defines the color for the display area background.
Ansi color controls	Enables ANSI color controls beyond their VT320 values of a black foreground (text) and white background. If your system displays less than 16 colors, or you are using a monochrome monitor, enabling this feature will cause "colored" text to be illegible. If your system has full color and you enable this feature, these color controls will function correctly for those applications that use them.
Use Ansi standard colors	The ANSI terminal specification defines eight colors for foreground and background with the default being black and white.  The emulator normally uses the default window colors specified in the Colors dialog in the Windows Control Panel, rather than black and white. If you enable this feature, the emulator will ignore the Control Panel color settings and always use black and white.  For most applications the foreground is black and the background is white, so enabling this feature will not affect most applications.
PC compatible	Enable this feature to allow text to be erased to the current host selected background color (PC style). Disable this feature to allow text to be erased to the default background color (VT style).


Emulation Setup

The emulator can only operate like the following terminals from Digital Equipment Corporation.

ANSI	Enables the emulator to emulate the VT320 terminal.  This is the default.

Control characters include carriage return (CR), form feed (FF), and escape (ESC).  Usually, the emulator does not display control characters.  You use control characters to make the emulator perform specific functions in data communication and text processing.


ANSI color controls

Defines the foreground and background colors for bold, blink, underline, and reverse video.  The ANSI color controls increases the emulator's color selection beyond the original 16 colors for the VT320 monochrome terminal.  Monitors displaying less than 16 colors will lose text if you enable this control.

ANSI standard colors Enables the standard black and white colors used by the VT320 monochrome terminal.


ANSI terminal

A video terminal that complies with prominent ANSI standards.


ANSI terminal specification

Character attribute

A characteristic (format) you can assign to a character that determines how the character appears on the screen.  Character attributes include bold, italic, underline, and so on.


Character codes

The codes produced with each key stroke and transmitted or received by the emulator.  A 7-bit coding system uses 7 bits to send each character to the host computer; an 8-bit coding system uses 8 bits.  The number of character codes varies with the type of character set.


Character set

A group of graphic and control characters stored as a unit in the emulator.  The emulator can display graphic characters on the screen as text and numbers.  The emulator uses control characters to perform special functions, such as printing text in the display area.

Control codes (C0 and C1 codes)

Binary codes representing control data, rather than graphic data, to perform non-printable functions, such as LF (line feed), CR (carriage return), FF (form feed), tab, bell, and so on.

•	C0 control codes are defined for 7-bit character sets.

•	C0 and C1 control codes are defined for 8-bit character sets.


Control function

A command used by an application or defined in a local function key to make the emulator perform a predefined action, such as move the cursor, delete a line, or change character sets.


Control sequence

The ANSI standards define the protocol for extending the meaning of character set data to be control data.  As such, a control sequence has a prefix called a control sequence introducer (CSI) followed by the command and its parameters.  For example,  Esc [ is the CSI used for 7-bit ANSI control sequences.


Coupling

A method for linking the cursor to the displayed text.  You can elect to have the right and left, and top and bottom, window borders move when the cursor moves beyond it.  This method keeps the cursor always visible.


CSI code

Data bits

Number of bits, 7 or 8, in each character transmitted or received.  In addition to the data bit selection, you can select a parity bit to increase the integrity of your data.  The default is 8 bits, no parity.  This setting should match the host computer.


Data Carrier Detect (DCD)

A modem control signal asserted by a modem to a PC, which usually indicates that the emulator established a connection to a remote modem.  DCD is also known as Received Line Signal Detect (RLSD) or Carrier Detect (CD).


Data Set Ready (DSR)

When this signal is ON, the modem is in the data mode and its control signals are ready.  DTR/DSR signals can be used for hardware flow control when they are not needed for modem control functions.  When modem control is enabled, do not select these signals.


Data Terminal Ready (DTR)

When the emulator is ready to accept more data, it turns this signal on.  When its receive buffer is full, the emulator turns this signal off.

A method of checking for data transmission errors between the emulator and the host computer.  For Even parity, the total number of bits must be even; for Odd parity, they must be odd.  The emulator and the host must use the same parity to reduce errors.


Port selection

The socket (COM1, COM2, or COM3) on the back of the terminal's system box to which you connect the communication cable.


Portrait

A term used to refer to a vertical page orientation, which is the opposite of landscape (horizontal page orientation).


Preferences

Settings that affect all sessions, such as the use of the mouse and warning bell, and how session windows are closed.


Print page

A routine that enables you to select the size of the print page margins and the number of lines per page.


Printer buffer

A temporary storage area used to hold data before it is sent to the printer.


Protocol

A set of rules and procedures for communication between devices. For example, Kermit is a file transfer protocol, and XON/XOFF is a flow control protocol for serial communications.


Rendition

The color scheme that you select for text attributes, such as bold, underline, and blink, and the screen background for the session.


Request to Send (RTS)

The emulator asserts this signal when it is ready for transmission to the modem.


RTS/CTS

See Request To Send (RTS) and Clear To Send (CTS).


Scrollback buffer

The area beyond the top margin where the emulator records information scrolled off the top of the page.


Select Graphic Rendition (SGR)

A mnemonic used for choosing colors.


Serial port

A connector on the back of the terminal's system box from which you connect to your host system.  Also, a logical route for data in or out of the terminal.


Session

A connection between a single virtual terminal emulator and a host computer.  In multiple application windows, each window contains a session with the same or a different host.


Session list file

A file that contains all the settings to create a terminal emulator sessions window.  The emulator uses the session list file to open subsequent terminal emulator session windows.


Session Support Utility (SSU)

A communication software utility on a host computer, that allows a terminal emulator to run multiple sessions without a terminal server over a single communication line.  OSF/1 and OpenVMS, operating systems from Digital Equipment Corporation, run SSU.


Session window

The area where information appears on the screen.  The operator and the host computer can enter information in the session window, which the emulator immediately stores in a scrollback buffer.  By default, the session window is 24 rows high and 80 columns wide, but you can change it from Display Setup in the Options menu .


Software application

A software program that performs a specific function, such as word processing.  A software application can be any program or sequence of instructions and routines that is not part of the operating system.


Special graphic character set

A 7-bit character set consisting of 94 graphic characters with special symbols and line drawing seqments.


Stop bit

A timing unit inserted between characters sent from the emulator to the host system.  You can select one or two stop bits to match the serial printer or host.


Supplemental graphic character set

An 8-bit character set consisting of 94 graphic characters including letters with accents and diacritical marks and special symbols.  Your emulator normally uses the DEC Multinational or ISO Latin1 character set.


Technical character set

A 7-bit character set containing scientific and mathematical characters used to write formulas and equations. It includes the Greek alphabet and mathematical symbols.


Telnet

A communication protocol used by terminal emulators to access a host computer using TCP/IP.


Terminal Device/Session Management Protocol (TD/SMP)

A communication protocol that allows two or more terminal sessions to share a single communication line if the system on the other end supports TD/SMP.  Most terminal servers and host computers, that run the Session Support Utility (SSU), support TD/SMP.  If you are using a terminal server, check its documentation to determine if it supports TD/SMP.


Terminator

A control character that signals the end of a line or a document.


Timestamps

Prints the time in milliseconds (beginning at the start of the session) of each character as it is typed and shows the elapsed time since the previous character was typed.  Used for checking the time between events in the communication stream.


Transmission Control Program/Internet Protocol (TCP/IP)

A network protocol used by UNIX-based computers.


U.S. ASCII character set

An 8-bit character set containing the standard characters and special symbols for the English language.  The U.S. ASCII character set combines with the DEC supplemental character set to make up the DEC multinational character set and with the ISO Latin-1 supplemental character set to make up the ISO Latin-1 character set.


UNIX

Operating system developed by Bell Labs.  (UNIX is a registered trademark of X/Open Company Ltd.)


User-Defined Keys (UDKs)

A function key that can be reprogrammed by the user or by a control sequence from the host.  Your terminal emulator defines the top row keys on the keyboard as UDKs.  You can increase the number of UDKs by preceding them with the Shift, Alt, or Alt-Shift keys.


Virtual terminal

A virtual terminal appears to be a real physical terminal to a host computer, but may share resources with other virtual terminals (keyboard and display) to create the effect of more than one terminal within a single device.  Virtual terminals maintain the full state and context of real physical terminals.  A terminal emulator session may be a virtual terminal.


VT keyboard

An LK450 (LK411) 108-key layout keyboard.


VT52

An emulation that uses two keystroke escape sequences; for example, Esc A moves the cursor up on a video terminal emulator.  This emulation and resulting software were used on the first video terminals from Digital Equipment Corporation.


What's in a word

Is all the alphanumeric and special characters on a keyboard that the emulator includes in a word when the operator uses a double-click of the mouse to select a word.

The default set are the characters that are valid in a VMS filename, including brackets ([ ]), the period (.), and the semi-colon (;).


Winsock

A multi-vendor standard for an application to access the services of the TCP/IP protocol suite.  This emulator uses Winsock to access Telnet services.


XOFF/XON

Control codes that the emulator uses to stop and resume transmission when its receive buffer (or the host's receive buffer) is full or empty.


XON/XOFF

See XOFF/XON.


Zoom

Restores the session window to it's default size and position.
