Terminal Type

Defines the type of VT emulation you want to use, which depends on the types supported by your host system.

The default is VT420_7_BIT.

Note: The VT-UTF8 terminal type is only supported for a VT100-like terminal.

Refer to VT 420 emulation limitations for more information.

Answer Back Message

Use this field to enter the message to send to the host when the host inquiry command is sent to the terminal.

VT ID

Virtual Terminal ID. The virtual terminal id is a character string used to identify the type of terminal to be emulated. The default value is VT420. To enter a different value use one of the following methods:

  • Basic method. Click Select... When the VT ID popup appears, click the value you want. Then click Apply to add the value to the VT ID field or click Cancel to cancel.

  • Advanced method. Do not click Select. Type the value you want directly into the VT ID field. For example, you might type vt100. Use this method if the value you want is not available through the basic method.

New-Line Operation

Specifies where the cursor will move when you press the New Line key.

  • Click CRLF if the cursor must move to the left margin on the next line.
  • Click CR if the cursor must move to the left margin on the same line.

The default is CR.

Backspace

Defines the default behavior of the backspace key; however, the actual action of the key is determined by the host application.

  • Click Backspace to send a standard ASCII backspace control-code (x'7F'). This moves the cursor backwards one position.
  • Choose Delete to send a standard ASCII delete control-code (x'08'). This moves the cursor back one position and deletes the character in that position.

The default is Backspace.

Local Echo

Specifies where characters are sent when you type them.

  • Click Yes to send characters to the host and to the display. Depending on how the host system behaves, you might get double characters on the screen.
  • Click No to send characters to the host and then back to the display.

The default is No, which means that characters will display only once.

Cursor

  • Click Normal to use the arrow keys to move the cursor to different positions on the screen.
  • Click Application to use the cursor keys to send control-code sequences that can be read by host applications. To determine whether the Application option is required, refer to the application's documentation.

The default is Normal.

Keypad

  • Click Normal to use the VT auxiliary keypad for typing numbers.
  • Click Application to use the VT keypad buttons to send control-code sequences that can be read by host applications. To determine whether the Application option is required, refer to the application's documentation.

The default is Normal.

Autowrap

Click Yes if text must automatically continue to a new line when it reaches the margin on the current line.

The default is No.

Reverse Screen Image

Select this option to reverse the foreground and background colors.

VT100 Function Keys

In VT100+ mode, the function keys generate ESC OP through ESC O[ sequences. By default it is disabled.

Lock

Check Lock to prevent users from changing the associated startup value for a session. Users can not change values for most fields because the fields are unavailable. However, functions accessed from the session menu bar or tool bar can be changed.
