Causes the display to reset some programmable parameters back to the

power-on state, which is defined as:

v Cursor on.

v Scrolling alphanumeric message off.

v All pixels of (all character positions are filled with X'20').

v Write position for next write is at position X'00' (top left).

v Default code page (437) selected.

v DC2 mode enabled.

v Default (Logic Controls) emulation mode selected.

v Brightness set to 100%.

v IBM user-defined characters are not erased. The Logic Controls user-defined character key

is reset.

All byte values between X'00' and X'1F' not defined in this section are ignored by the display in Logic Controls

mode. User-defined characters in the IBM mode that have not been defined previously are spaces.

APA commands

This section describes the following APA VFD commands: v Backspace Without

Deleting v Line Feed v Carriage Return v Clear Display v Display Position v Delete to

End of Line v Dimming v Cursor Mode v Screen Mode v Horizontal Scroll v Display

Mode v User Definable Font v Graphic Display Mode v Double Size Letter in

Horizontal v Character Code Set of Full Size Letter v Character Code Set of Half Size

Letter v Horizontal Scroll on All Lines v Font Selection

Note:

The command code format shown in the following topics is in hexadecimal

format.

Backspace without deleting

Purpose:

The write-in position is shifted to the left one digit and the displaying screen is

not changed. This command is ignored when the write-in position is on the

least significant digit.

Line feed

Purpose:

The write-in position is shifted to the next row on the same digit position. If the

write-in position is on the bottom row, the displayed character is scrolled up to

the upper row and all characters on the bottom row are cleared. The write-in

position is not changed. The displayed character under the screen mode of the

24x24-dot 1 row+16x16-dot 2 rows is not scrolled up from the row of 16x16-

dot format to 24x24-dot.
