DEC Emulations

HostAccess supports the following DEC terminals: VT52, VT100, VT220, VT320 and VT420.

You can configure the DEC terminal in two stages, an initial stage and an advanced stage.

The initial configuration stage allows you to define the screen size and display mode, i.e. which colours will be displayed.

You can either select a predefined screen size or define your own.

To define your own screen size:

Enable Custom, then type or select the number of Columns and Rows you want:

To set the Display mode, choose one of the following options:

Colour

HostAccess's default colour settings.

Colour + flash

As Colour but with flash enabled. This is flashing text programmed by the host, usually for information or emphasis.

Green

Green on black, this is the standard dumb terminal setting.

Amber

Amber on black.

White

White on black.

Sculpted

This gives a Windows look and feel.
Note: You can modify these colours, see Configuring Screen Attributes.

Click on the Advanced button to configure the advanced options.

DBCS Host Encoding:

Host encoding refers to the "nationality" of the terminal and changes the codepage to be used for displaying the data.  Select the DBCS (Double Byte Character Set) from the list of supported encoding tables.

Advanced Options

Select the options as follows:

User Keys

Select Locked or Unlocked to lock or unlock function keys.

Cursor keys

Select Normal or Application to select the response the key should send to the host ( this option should be set by the system administrator only).

Backspace key

Select Backspace or DEL to define the character sent to the host when you press the backspace key.

Keypad keys

Select Numeric or Application to choose whether keypad keys have their normal numeric function, or are specific to an application ( this option should be set by the system administrator only).

Answerback

Use Answerback to specify a message to be returned to the host from HostAccess when the host requests an answerback message.

Auto-wrap

Select Auto-wrap to wrap text around the screen.

Use NRC (7 Bit) characters

Select Use NRC (7 Bit) characters to determine whether printed characters will be mapped by the Nationality setting (see below)

Graphics mode

Select Graphics mode to pre-load DEC’s graphics table, instead of a standard ASCII table.

Nationality

Select the nationality of the emulation.
