OPERATION
3.2.2 Displaying All Characters
Usually, only alphabet and numeric characters are displayed when entered. Pressing the
CTRL key, the ESC key, the Backspace key or similar keys enters a code but no character
is displayed. These characters may be displayed however (see Appendix H for a list of the
characters and their meaning).
To display but not interpret all characters (sometimes called "monitor mode"), including
escape sequences and control characters, enter one of the sequences
ESCU
CTRL/1
To return to the usual display of characters, enter one of the sequences
ESCX
CTRL/2
ESCu
3.2.3 Double Size Characters
The terminal is capable of displaying characters twice the height and/or twice the width of
standard-size characters.
The basic procedure is
1. Move the cursor to the desired row.
2. Enter the escape sequence for the desired size. Characters already on the
row or characters you then type onto the row will have the desired size.
Double-High
A double-high character is formed using two adjacent rows: the top half of the character
appears on the higher row, the bottom half appears on the lower row. Thus, to get the
resulting effect of double-high characters, the same characters must appear twice, once
on each row.
To enter the top of the each character:
1. With the cursor on the upper row, enter the sequence ESC m 1
2. Type in the desired characters.
To enter the bottom half of each character:
1. With the cursor on the lower row, enter the sequence ESC m 2
2. Type in the same characters as above.
To return to a row of double-high characters to single-high characters,
1. With the cursor on the appropriate row, enter the sequence ESC mO
