   VT100 Help

VT100 allows you to log on to a remote host via the TELNET protocol and process commands as if you were at a directly connected terminal.  VT100 provides terminal emulation so that communication and presentation of data are made in an understandable manner both for you and the remote host.  VT100 provides emulation of VT100/101/102 terminals.

Compose Characters
  Composing Characters

To generate special characters which cannot be generated directly from your keyboard, you must compose them by pressing the Compose key.  You can then type a valid compose sequence to generate a compose character.

Because the Compose key is not directly available on the PC keyboard, the function key F6 on the PC keyboard can be mapped to the Compose key.

For more information see

To compose characters not directly available from the keyboard, follows these steps:

Use Fonts on the Preferences menu to select a language other than US.  Be sure to select National Mode using the checkbox.  For more information on this procedure, see: .

On your actual keyboard, press F6 key.

Using the table provided below, generate the desired character by pressing the corresponding key sequence from the Sequence column.  The order of these keys is not important, except for those characters noted by a "*".

Profiles can be created from the default factory settings as well as from an existing profile, so you can start a new profile from scratch or base it on an existing profile.  Profiles names can be as simple or descriptive as you like, as long as they are unique, making the method of connecting to the remote host very "user-friendly".  (Note that profile names are case-insensitive, so Name and name would not be considered unique).

Complete access to the list of profiles is available through the File menu or through the Connect dialog.  This allows settings to be changed quickly and easily, letting you switch from one session to the next just by choosing a new profile.  If any changes are made to the loaded profile (i.e., any of the above settings are modified), you will be prompted to save them whenever you attempt to load a different profile, create a new one, or exit the application.  A profile can also be deleted, providing it is not currently in use by another instance of the application.

Proper graphical representations of the control codes in the Display Control mode are available only in the "FTC-SansSerif" font.

Note: Choosing a font which is application specific and non-standard (so far as Windows is concerned) might lead to unpredictable visual effects.

Size

Used to select the point size of the currently selected font.  (See above for a description of FTC font sizes.)

Language

Used to set VT100 for operation with a national character set.  You should first set up your version of Windows to recognize your keyboard as a national keyboard.  This is done through International settings in the Windows Control Panel.

National Mode

If you select to work in non-National Mode, VT100 generates DEC multinational codes to correspond to your national set.  If you select National Mode, VT100 generates DEC National Replaceable codes.  This choice may be dictated by the application you are using.  Note that National Mode must be selected for the Compose Characters feature to function properly.

Sample

Displays a text sample using the currently selected font and font size.

Fit Font to Window At

This feature allows you to enable automatic scaling of fonts to fit the current VT100 window size.  You can also set the number of columns that are to fit in the VT100 window when automatic scaling of fonts is enabled.  Note that the automatic scaling feature is disabled for raster fonts.  Note also that the automatic scaling feature is not supported in Windows 3.0.

Command-Line Parameters
  Command Line Parameters

If you frequently need to run VT100 with the same default parameters, you may create additional VT100 icons for connecting to various hosts and specify different default parameters for each.  Follow these steps:

Click once on the VT100 icon.

Select Copy from the File menu of Program Manager and choose New Program Item to create a new copy of the VT100 icon.

Select Properties from the File menu of Program Manager to change the Command Line and Description for the new icon.

The VT100 command line has the following syntax:

VTTERM [-d<profile-name>] [-h<hostname>] [-p<port-no>] ]-t]

where

<profile-name>	Name of the profile to load on startup.  The profile-name must already exist.  If a profile-name is not specified, an (Untitled) profile having the default factory settings is loaded.  Note that even if there is a hostname associated with the given profile, a connection will not automatically be attempted to that host; the optional <hostname> parameter must be specified as well.

<hostname>	The hostname or Internet address of the remote host to which you wish to connect.  If a valid <hostname> is specified on the command line, connection occurs immediately.  Otherwise, no automatic connection attempt will be made.

<port-no>	The port number to use when connecting.  A port number may be specified on the command line without a hostname when a special port is needed for several sessions but a different host is to be used for each.  If no port number is specified, the default Telnet port (port 23) is assumed.

The -t flag specifies whether Telnet negotiation will be done on a non-Telnet port; i.e., a port other than the default of 23.  This option is only necessary when connecting to a Telnet server on a non-Telnet port.  This option applies only to non-Telnet ports because Telnet negotiation will always be done on the Telnet port.  If this option is not specified, the default is to use Telnet negotiation on the Telnet port, and not to use negotiation on all other ports.

You may establish a VT100 session using the Connect command on the Connect menu, or by pressing the Connect button on the button bar.

Hostname

Enter the name of the remote host to which you wish to connect, or use the drop-down listbox to select a name from those previously entered.  The name must be a valid hostname, alias, or IP address on the network.

Profile

Enter a profile name or select one from the drop-down listbox.

	If the profile you select has a hostname and/or port number associated with it that DIFFERS from the hostname and/or port you have entered manually, your choices will be overridden by those of the profile.
If you select the Default profile, the factory settings will be loaded.  For more information, see:

Port

Enter a port number to be used for the connection.  The default port number is the standard Telnet port (port 23).

Note that spontaneous disconnection may occur if the Telnet connection is lost.  Some remote hosts may abort the connection if you fail to log in within a specific time.  Some hosts will abort the connection immediately after you log out - if you wish to log in as another user you may have to connect once again.

  Pausing the Screen Display

When you are connected to a remote host, you may freeze the terminal display by using the Pause button on your keyboard or by using Ctrl+S.  To resume the screen display, press the Pause key again or use Ctrl+Q.  Pausing the screen is typically done when a large amount of data is being continuously displayed and it is rapidly scrolled off.  Pausing the screen will put a temporary "hold" on incoming data.  The title bar will indicate the "paused" status.  To view data that has already scrolled off the screen, use the vertical scroll bar.

If the remote host needs to be able to receive Ctrl+S or Ctrl+Q, then you must disable the Local XON/XOFF option, which can be done by selecting Terminal Params from the Preferences menu.

Print Setup
  Printing Tab

VT100 supports continuous printing as well as non-continuous "snapshot" printing.  To activate continuous printing, select either Print Controller Mode or Auto Print Mode, then choose the Continuous Print option under the File Menu.  When continuous printing is on, this option will appear checked.  Continuous Printing is automatically disabled if neither of the two modes are selected, or if there is an error during printing.  If there is an error during continuous printing, rectify the cause of the problem, then resume continuous printing by reselecting the Continuous Print option.

Non-Continuous Print Extent

For non-continuous "snapshot" printing, you may choose how much data is to be printed.  The choices are:

Selected Text - Selected portion of the screen.

Entire Screen - Entire screen (24 lines) starting from the first visible line in the window.

Entire Buffer  -  The entire scroll-back buffer.

Non-Continuous Print Style

For non-continuous "snapshot" printing, you may choose from the plain text or bitmap styles of printing.  Print Style governs the style of printing for your print requests as well as requests received from the remote.  If the bitmap style is selected, you may choose "Reverse Video" (using "Preferences, Terminal Parameters") to print data with foreground and background colors swapped.  If Continuous Printing is enabled and you switch to bitmap style, any further change to the Print Style will be effective only after Continuous Printing is stopped.

Continuous Print Mode

Print Controller Mode

If this mode of continuous printing is selected, characters are sent to the printer without being displayed on the screen.  The characters NUL, XON, XOFF and those sequences that set and reset this mode are not sent to the printer.  If both Auto Print Mode and Print Controller Mode are selected, the latter takes precedence.

Auto-Print Mode

If this mode of continuous printing is selected, display lines are automatically printed when you move the cursor to the next line (using a line-feed, form-feed, vertical tab or autowrap).

Setup

Click this button to access the Windows Printer Setup dialogs.  At least one printer must be properly configured.
