Keyboard Control
Table 3-1. ENTER Key Operation
CHARACTER MODE
The cursor is repositioned to column O.
All characters through the first subsequent block ter-
minator or non-displaying terminator or through the end
of the line (whichever is encountered first) are transmitted
to the host computer as a block.
ASCII control codes, video enhancement escape sequences,
alternate character set escape sequences, and field defini-
tion escape sequences are all transmitted if encountered.
If the operation is terminated by encountering the end of
the line, the terminal sends a
<CR>
(or a
<CR><LF>
ifauto
line feed mode is enabled). The cursor is repositioned to
column 0 and a line feed is performed if auto line feed mode
is enabled.
If the operation is terminated by encountering either a
block terminator or a non-displaying terminator, the ter-
minalsends a block terminator followed by a
<CR>
(or a
<CR><LF>
if auto line feed mode is enabled); the cursor
remains positioned immediately following the terminator.
If there is no data to be transmitted, the terminal sends a
block terminator followed by a
<CR>
(or a
<CR><LF>
ifauto
line feed mode is enabled).
The type of handshaking used is determined as follows:
inhHndShk(G) = YES
I nh DC2(H) • NO - - -

CHARACTER MODE, FORMAT MODE
If the cursor is within an unprotected field, all characters
. from the current cursor position through the end of the
field are transmitted to the host computer as a block.
Otherwise the terminal searches for the next subsequent
unprotected field and transmits the content of that field.
ASCII control codes within the field are transmitted.
Video enhancement escape sequences, alternate character
set escape sequences, and field definition escape sequences
within the field are NOT tr.ansmitted.
If the operation is terminated by encountering the end of
the unprotected field, the terminal sends a
<CR)
(or a
<CR><LF)
if auto line feed mode is enabled). The cursor
remains at the first character position after the end of the
field.
If the operation is terminated by encountering either a
block terminator or a non-displaying terminator, the ter-
minal sends a block terminator followed by a
<CR)
(or a
<CR><LF>
if auto line feed mode is enabled); the cursor
remains positioned immediately following the terminator.

BLOCK LINE MODE
Auto Term(J) = NO
inh DC2(H) = YES
The cursor is repositioned to the leftmost character
position (column zero) within the current line. All
characters through the first subsequent block ter-
minator or non-displaying terminator or through the
end of the line (whichever is encountered first) are
then transmitted to the host computer as a block.
Auto Term(J)" NO
inh DC2(H) = NO
The cursor is NOT repositioned. All characters
through the first subsequent block terminator or non-
displaying terminator or through the end of the line
(whichever is encountered first) are transmitted to the
host computer as a block.

Term( J) = YES.
The terminal inserts a non-displaying terminator at
the current cursor position and then moves the cursor
backward to the previous block terminator or non-
displaying terminator (or homes the cursor if none is
found). All characters from the new cursor position
through the end of the line, the next subsequent block
terminator, or the newly inserted terminator
(whichever is encountered first) are then transmitted
to the host computer as a block.
Note that ifthere is already a non-displaying terminator at
the cursor position when the
II
key is pressed then the
cursor remains at that position and no data is transmitted.
ASCII control codes, video enhancement escape sequences,
alternate character set escape sequences, and field
definition escape sequences are all transmitted if
encountered.
If the operation is terminated by encountering the end of
the line, the terminal sends a
<CR)
(or a
<CR><LF>
ifauto
line feed mode is enabled); the cursor is repositioned to
column 0 and a line feed is performed if auto line feed mode
is enabled.
If the operation is terminated by encountering either a
block terminator or a non-displaying terminator, the ter-
minal sends a block terminator followed by a
