The Settings - Display Tektronix Page

Use the options in the Tektronix page and the Graphics page to control the appearance of Tektronix graphic images. Many of these options correspond to the options available on the Tektronix 401X series terminals.

To manually enter (or exit) Tektronix mode

  1. In a VT 340 session, from the Options menu, choose Settings.

  2. In the Settings dialog box under Categories, choose Display.

  3. To enter Tektronix mode, in the General page under Terminal, select 401X.

    -or-

    To exit Tektronix mode, in the General page under Terminal, select a value other than 401X.

    NOTE:If the VT640 Compatible option in the Tektronix page is selected, the Retrographics VT640 extended drawing modes and control codes to enter and exit Tektronix mode are also supported.

Options

Description

CR Effect

Specify the action to take when a CR is received. CR, the default, moves the cursor to the current margin. CR LF moves the cursor to the current margin, then down one line.

LF Effect

Specify the action to take when an LF is received. LF, the default, moves the cursor down one line. LF CR moves the cursor down one line, then to the current margin.

BS Effect

Specify the action to take when an ASCII BS is received. BS, the default, backspaces the cursor. Delete backspaces the cursor and erases the character. The 4014 uses a storage-tube display, and cannot erase individual characters.

DEL Effect

Specify the action to take when a DEL is received. LowY, the default, processes the DEL the same as any other received character. Ignored does not process the DEL. Use this value if your host sends DEL as a pad character.

GIN Terminator

Select the GIN position report terminator code. None, the default, sends no terminator code(s) at the end of the report, CREOT sends control codes CR and EOT following a position report, and CR sends only a CR.

VT640 Compatible

If selected, the VT640 sequences for entering and exiting Tektronix mode are interpreted.

Characters

Select the size of displayed characters. Aligned, the default, uses 4014 character sizes. Enlarged uses enlarged, easy-to-read characters. Enlarged characters do not align exactly with graphics.

Font Type

Select the type of font to use for displayed characters. Bitmap, the default, uses the built-in bitmap fonts for Tektronix characters. In most cases, this provides better looking characters than the Vector setting, although the character size might be less accurate. Vector generates characters from a vector definition of the characters, much like the Tektronix 4010/4014 device.

Overwrite

Select Transparent mode (the default) to overwrite existing characters without erasing them. Or, select Destructive mode to erase existing characters (including spaces) before overwriting the area.

Character Set

Select the character set to use. ASCII, the default, uses the ASCII character set, which the host cannot change. APL uses the APL character set, which the host cannot change. Prog uses a character set that the host can change with control codes.

Line Style Map

Map the standard 4014 line styles to Windows colors. Style, the default, uses normal line styles and does not perform color mapping. Color maps line styles to colors; all lines appear as solid lines. Select Both to map line styles to colors and maintain original line styles.

Margin Control

Select the setting for Page Full Condition. This option is equivalent to the MarginControl switch on a 4014. None, the default, never sets the Page Full Condition. After a page fills, writing continues at the top without clearing the screen. Select 1 to set the Page Full Condition when the cursor reaches the bottom of the first margin, or 2 to set the Page Full Condition when the cursor reaches the bottom of the second margin.

Auto Print

Determine whether to produce a hardcopy each time the Page Full Condition occurs. This option is equivalent to the AutoPrint switch on a 4014. Disabled, the default, does not produce a hardcopy. Enabled produces a hardcopy. The screen clears when the hardcopy finishes printing.

Display

Control the size of the emulation screen used to display the Tektronix image. Select 64x24, the default, to display the image using 64 of the 80 available columns. This setting gives a true aspect ratio. Select 80x24 to display the image using the full emulation window. This makes the image larger and easier to read. Or select 80x30 to display the image using all 80 columns, and extend the image vertically to the equivalent of 30 VT lines. This keeps the aspect ratio correct and also makes the image larger and easier to read.

To map line styles to color

  1. In a VT 340 session, from the Options menu, choose Settings.

  2. In the Settings dialog box under Categories, choose Display.

  4. If you want to change the actual colors displayed for the 4100 series color indexes, choose the Color tab.

    The eight 4010/4014 line styles are mapped to the closest Windows line styles. Tektronix and this application support eight line styles. The VT340 supports only five line styles.Changing the line style map does not affect the images already drawn on the screen. You can also map characters to colors because they use the solid attribute.
