Keyboard & Mouse Tab for IBM 3151 Terminals

Getting there

Open a VT terminal session and then open the Settings dialog box.
Under Terminal Configuration, click Configure Terminal Settings.

Keyboard modes

Auto repeat

Select to make most keys repeat when pressed. The Shift, Return, and Ctrl keys do not auto repeat.

Break enabled

Select to enable the Break function. When cleared, both the Break command and the VtF5 (Break) keystroke (Ctrl+Break) are disabled.

Local echo

Select to cause each character typed at the keyboard to be immediately displayed on the screen. When you're communicating with the host computer, each character typed at the keyboard is transmitted to the host. Most host systems (for example, a VAX running VMS) immediately send the same character back to the terminal (that is, echo the character). The character is not displayed on the screen until it is received back from the host.

When you're online and you select this option, each character is sent two places: directly to display memory (the screen), and to the host computer. On an echoing host system, this means that each character you type appears twice on the screen. Select this option only when communicating with host systems that do not echo each typed character; for example, some public networks.

Bells

Margin bell

Select to have your computer beep when the cursor is eight characters from the right margin.

Warning bell

Select to have your computer beep when the ASCII bell character (Bel, decimal 7) is received from the host or entered from the keyboard.

To disable the format bell (which beeps, for example, when Reflection encounters an unprotected field), clear the Warning bell option.

Terminal keys

Select how the following keys act when pressed under IBM 3151 emulation.

Send Key	The default value transmits the entire page to the host. Select Line to have Reflection transmit only the selected line to the host.
Return Key	The default value transmits a newline request to the host. Select Field to have Reflection move to the next field of a formatted screen.
Enter Key	The default value acts as a Send key. Select Return to have the Enter key act as a Return key.
Backspace Key	Select a value to send when the Backspace key is pressed. The values available represent the unshifted/shifted states you can choose from. For example, selecting BS/DEL means pressing Backspace sends a Backspace to the host. Pressing the Shift key and then pressing Backspace will send a Delete to the host.
	This value	Designates
	BS	Backspace, ASCII 8.
	DEL	Delete, ASCII 127.
	CAN	Cancel, ASCII 24.

Keyboard shortcuts

NOTE:Settings in the Keyboard Mapper override these options.

Standard File and Edit menu shortcuts	Select to enable the following keyboard shortcuts:
	PC keystroke	Terminal function
	Ctrl+A	Select All
	Ctrl+C	Copy
	Ctrl+F	Find
	Ctrl+Shift+F	Find Next
	Ctrl+O	Open File
	Ctrl+P	Print File
	Ctrl+V	Paste
	Ctrl+X	Cut
Hold Screen shortcuts	Select to have Reflection use Ctrl+Q to start and Ctrl+S to stop the processing of data from the host. Clear Hold Screen shortcuts if you use a host application (such as EMACS) that requires the use of the Ctrl+S and Ctrl+Q characters. Clearing this option allows the Ctrl+S keystroke to send to the host a Ctrl+S character (ASCII decimal 19), and the Ctrl+Q keystroke to send to the host a Ctrl+Q character (ASCII decimal 17).

Mouse shortcuts

Always copy selected text to the clipboard	Text selected using the left mouse button and drag action is copied to the Clipboard when you release the mouse button.
Right-click pastes clipboard text	The contents of the Clipboard are pasted into Reflection at the cursor location when the right mouse button is clicked. NOTE:Settings in the Mouse Mapper override these options.
Middle button pastes clipboard text	The contents of the Clipboard are pasted into Reflection at the cursor location when the middle mouse button is clicked. NOTE:Settings in the Mouse Mapper override these options.
Rectangular Selection	Dragging the mouse across an area selects only the text within that area. When this option is cleared (unchecked), the selection wraps to line ends.
