The foreground and the background colors can be controlled
independently. The high intensity attribute is ignored. The underline
appears in the same color as the foreground. The underline cursor
appears in white. The block cursor causes the foreground color to be
replaced with the background color and vice versa. The field attribute
positions are displayed in the background color. The divider line is
displayed in blue, and characters/symbols in the operator information
area are displayed in green. In the case of the reverse attribute, the
foreground color is changed to background color and vice versa.
The character color attribute is effective only in Program Color mode.
Each character can be individually displayed in any of the above eight
colors. The foreground and the background color can be controlled
independently.
If the page is unformatted in Program Color mode, the black and green
color attributes are used as default background and foreground color
attributes respectively.
The underline symbol appears in the same color as the foreground. The
underline cursor appears in white. In the case of the reverse attribute,
the foreground color is changed to the background color and vice versa.
If this option is on, the tab stops can be set at any character position in
each viewport regardless of the field attribute character position.
If this option is off, the column tab stops are ignored and the tab
operation depends on the field attribute character position.
Refer to the description of the Return key.
Refer to the description of the Insert Character key.
The Auto Line Feed option, when on, causes the cursor to move to the
first character location of the next line when the operator presses the
Carriage Return (CR) key or when the CR character is received from the
host.
When this option is off, the cursor moves to the first character location
of the current line. Therefore, if the new line function is desired, the host
must send (or the operator must enter) the CR and LF characters.
The Line Wrap option, when on, causes the cursor to move to the first
character location of the next line in the page, after it reaches the last
character location of the current line in the page. If the Scroll option is
also on, when the cursor reaches the last character location of the
bottom line in the unformatted page, the page data scrolls up, and the
cursor moves to the first character location of the newly created bottom
line. If the Scroll option is off, the cursor goes to the top of the page.

When the Line Wrap option is off, the cursor does not advance to the
first character location of the next line. Instead, it stays at the last
character location. In this case, the audible alarm sounds whenever the
operator enters data at the last character location. If additional
characters are entered, they are transferred to the host and the displayed
character in the last character position changes as each character is
entered.
The Line Wrap option is automatically set to on in block mode.
Two types of scroll operations are available; jump scroll and smooth
scroll. Smooth scroll allows the terminal to move the data up/down at
an even rate of 4 rows per second.
