6.1 Configure Display Settings

You can customize host foreground and background colors, set up hotspots and map keys to make it easier to navigate the host application, as well as specify other host-specific options. These settings are specific to the session you are configuring.

How do I?

6.1.1 Customize host screen colors

You can customize the color of your screen and the appearance of different host attributes in the terminal window. For each item, you can select a color for the foreground and the background colors for 3270, 5250, VT and UTS host connections. Colors are specified using the color grid or by entering the Hex code format.

There are many web sites that list available Hex colors, for an example see w3schools.com HTML Color Picker

You may see different options depending on the type of host connection.

Options available to UTS hosts:

Use color information from the host - To use the colors specified here rather than any colors specified by the host, clear this option.
Enable blink - To disable blinking, clear this option.
Select attribute to edit - In UTS emulation, colors are set directly by the host. You can specify colors for text associated with specific screen display options. Including the following and available combinations:

Plain, Underline(UND), Strikethru (STK), Left Column Separator (LCS), Control Page, and Status Line (OIA).
Video intensity - The video intensities, Blink, Dim, Protected, and Reverse are combined with the attributes to create additional combinations. For example, you could map foreground or background colors to all cells with Dim + Blink + Underline or Reverse + Protected + Strikethru + Underline.

When you select a video intensity (or combination of intensities), those intensities are combined with the value of the attribute drop down list to form a single color mapping.

Options available to VT hosts:

Enable blink - To disable blinking, clear this option.
Enable bold - Displays text set with bold attributes as bold text in the terminal window. To display bold characters as plain text, clear this option.
Enable underline - Displays text with underline.
Inverse video - This option reverses the foreground and background colors when the VT host sends an inverse video escape sequence. If this option is not enabled, the inverse video sequences sent from the host are ignored.

To customize colors for all host types:

From the left navigation panel, click Display.
Under Color Mappings, click the background color field to open the color grid. From the color grid, select the color you want to use as the host background color. Alternatively, type the Hex color number for the color you want to use.
From the drop down list, select the default host color you want to change.
Open the color grid for the Foreground to choose a color to map the new color for the text or type the Hex code you want to use. Select Background to map the new color to the background field.
Click Save to close the Display panel and resume configuring your host connection.

Restore defaults clears any changes you made and resets the colors to the default host settings.

6.1.2 Configure hotspots

Hotspots are buttons that appear over common host commands in terminal sessions. When you use hotspots you can control the terminal session using a mouse or a finger-tap instead of the keyboard. The hotspot transmits a terminal key or command to the host. By default, hotspots are configured for the most common 3270, 5250, and VT commands.

Hotspots are enabled and visible by default, however you can disable hotspots for a particular session or choose to hide them.

Enable hotspots

Choose No to disable hotspots for the session you are connecting to.
Show hotspots

Choose No to hide hotspots on the screen. Hotspots remain functional.

Table 6-1 Hotspots for 3270 Hosts

Hotspot	Description
PF1...PF24	Transmits a PF1...PF24 to the host
PA1, PA2, or PA3	Transmits a PA1, PA2, or PA3 to the host
enter	Transmits an Enter key to the host
more	Transmits a Clear key to the host

Table 6-2 Hotspots for 5250 Hosts

Hotspot	Description
enter	Transmits an Enter key to the host
more...	Transmits a Roll Up key to the host (scrolls down one page)
PF1 - PF24	Transmits a PF1...PF24 to the host

Table 6-3 Hotspots for VT Hosts

Hotspot	Description
F1 - F20	Transmits a F1...F20 to the host

6.1.3 Configure screen dimensions for VT and UTS hosts

As an administrator you can select the number of columns and rows for VT and UTS sessions.

Open the Display panel.
Under Dimensions, specify the number of columns and rows you want each screen to possess. The default values are 80 columns by 24 rows.

Select Clear on host change to clear the terminal window and move the contents to the scrollback buffer when the column size changes. (VT-only).
Click Save.

6.1.4 Set cursor options

Use the cursor options to configure the appearance and behavior of the cursor and ruler.

This option	Does this....
Cursor type	Underline displays the text cursor as an underline. Vertical bar displays the cursor as a vertical line. Block displays the text cursor as an inverse video block.
Ruler type	Vertical displays a vertical ruler at the cursor position. Horizontal displays a horizontal ruler at the cursor position. Crosshair displays both a horizontal and vertical ruler at the cursor position.
Cursor color	Click the color field to open the color grid. From the color grid, select the color you want to use as the color of both the cursor and ruler. Alternatively, type the Hex color number for the color you want to use.
Cursor blinks	By default, the cursor (whether in block or underline mode) blinks. Clear this option to display a visible non-blinking cursor.

6.1.5 Set VT scrollback buffer options

The VT scrollback buffer contains the data that has scrolled off the display and is no longer accessible by the host computer. When a scrollback buffer exists, you can view it by using the vertical scroll bar.

The scrollback buffer is enabled by default. When enabled, the session maintains a buffer of lines that have scrolled off the terminal screen. This option is available to all users when they are granted permission to modify Terminal Display Settings by the administrator.

This option	Does this...
Scrollback row limit	Limits the number of rows held in the scrollback buffer. The default setting is 500 rows.
Save display before clearing	When selected (the default), the data on the terminal display moves into the scrollback buffer when you, or the host, clear the terminal display. If you prefer not to have the terminal display saved to the scrollback buffer, clear this option; when the terminal display is cleared, the data is discarded.
Save from scrolling regions	When top and bottom screen margins are set (for example, by a text editor such as EDT or TPU, or with the DECSTBM function) the area within the margins is called the scrolling region. When this option is cleared, scrolling text within this region isn’t saved to the scrollback buffer. Select this option to save information within scrolling regions to the scrollback buffer. Note: This can cause display memory to fill quickly.
Save before clearing from any row	This setting specifies whether data that has been cleared from a portion of the terminal window is saved in display memory.
Compress blank rows	Select this option to save room in display memory by compressing multiple blank rows into a single blank row.

6.1.6 Set keyboard options

You can set the following keyboard options:

Backspace sends (VT)

Configures the function that the Backspace key sends. On the VT terminal keyboard the back arrow key (<x) is configurable: it can send either a delete (ASCII 127) or a backspace (ASCII 8) character.
Cursor keys

Controls the characters that the four arrow keys (on both the numeric and editing keypad) transmit. This setting is typically set by the host. In general, you should keep this set to Normal.

If the arrow keys aren’t working properly, it may mean that this option remained incorrectly set to Application when a host program terminated abnormally. Changing this setting back to Normal should fix the problem with the arrow keys.
Keypad

Controls the characters that the numeric keypad keys transmit. This setting is typically set by the host. In general, you should keep this set to Numeric.

If the number or PF keys aren’t working properly, it may mean that this option was incorrectly left set to Application when a host program terminated abnormally. Changing this setting back to Numeric should fix the numeric keypad.
Local echo (VT)

This option causes each character typed at the keyboard to be displayed on the screen. This option is cleared by default, because most hosts echo back received characters.

6.1.7 Configure terminal settings

The following terminal settings are specific to VT host types.

Terminal type (VT)

Specifies which terminal should be emulated. These choices affect the codes generated by the numeric keypad, the interpretation of control functions, and the response to terminal identification requests.
Terminal ID (VT)

Specifies the response that Reflection ZFE sends to the host after a primary device attributes (DA) request. This response lets the host know what terminal functions it can perform. This setting is independent of the terminal type setting. When set to the default value of Reflection, Reflection ZFE responds to a primary DA request with the set of features it supports. If your host requires a more specific terminal ID, select another value from the list.
New line (VT)

Select this option to send both a carriage return and linefeed when you press Enter. When Reflection ZFE receives a linefeed, form feed, or vertical tab, it moves the cursor to the first column of the next line. When this option is cleared (default), the Enter key sends only a carriage return. A linefeed, form feed, or vertical tab received from the host moves the cursor down one line in the current column. If lines on the display keep getting overwritten (that is, the host is not sending a linefeed along with a carriage return), select this option. If the New line option is selected but the host does not expect to receive a linefeed with each carriage return, lines will be double-spaced on the display.

6.1.8 Set other display options

Some display options are host-specific as noted below. When the host type is not indicated, the options apply to all supported host types.

This option	Does this....
Input field underlining (3270, 5250)	You can determine how the underlining of host input fields is handled: Host controls underlining of input fields (Default) Always underline input fields Never underline input fields
Status line (VT)	To enable a status line at the bottom of the display. Choose: None to disable the status line. (Default) Indicator to display the page, cursor position, and printer status. Host Writable to have the host application display information in the status line.
Preserve aspect ratio	Select this option to maintain the host screen aspect ratio regardless of the size of the browser window. Aspect ratio describes the proportional relationship between the width of an image and its height.
Display OIA (3270, 5250)	Select this option to display the operation and status messages in the Operator Information Area (OIA) at the bottom of the terminal window . By default, OIA display is enabled.
Ignore mouse click on window activation	When a mouse click activates the terminal window, this option specifies whether actions such as updating the terminal cursor position, clearing a selection, or executing a hotspot are also performed. By default, these actions are not performed.
Auto wrap (VT)	When selected, characters automatically wrap at the right margin and continue on the next line. When cleared, characters do not wrap when they reach the right margin of the display. New characters overwrite the character at the right margin until a carriage return is entered.
