Keyboard Mapping

The illustration on the following page shows where DG 410/412 keyboard functions are mapped to keys on the 101/102 key Enhanced AT keyboard layout. Special key functions that are provided on the DG 410/412 keyboard can be mapped to any key on your keyboard by using the DG virtual key names listed in the Define Keyboard Macros dialog box.

Key Functions

Local Print

The Local Print key is used to print the current window or initiate the Print Form operation. You can print the contents of the current window starting with the row containing the cursor by pressing the Local Print key on its own. Keyboard entered data will be ignored while the print is in progress. You can abort the print operation by pressing the Local Print key again.

You can initiate the Print Form operation by holding down the Shift key then pressing Local Print. This performs the same function as Local Print pressed on its own, except that only data appearing at full intensity will be printed when protected text is disabled. When protected text is enabled, only unprotected text will be printed.

Cursor Type

This key enables you to change the appearance of the cursor. By default the cursor is displayed as a reverse video block. Pressing and releasing the Cursor Type key one or more times will cause the cursor display to change in the following order:

Blinking underline
Invisible cursor
Blinking reverse video block
Non-blinking reverse video block (default)

N/C

Pressing this key will cause the display of the current text region to toggle between normal and compressed character spacing mode. In normal mode the display is 81 columns wide. Pressing the N/C key once will change the display width to 135 columns. Note that the margins will not be affected by this key.

Enhanced AT Keyboard Layout

Composing Characters

The Data General D410 keyboard has a SPCL key which enables you to generate characters from the DG International character set. You can generate the same characters by using the method described for the DEC emulation. Refer to the Compose Character Sequences section in the Keyboard Configuration chapter for details.

Key Codes

The following table lists the decimal value of codes generated when keys that emulate those found on the Data General keyboard are pressed alone or in conjunction with the Shift and/or Ctrl keys.

Note that each code shown is the second code generated when the key or key combination is pressed, the first always being the code RS (Hex 1E).
