BLOCK PAGE MODE, FORMAT MODE
AutoTerm(J) zNO
Inh DC2(H) =YES
The cursor is repositioned to the "home up" position.
All unprotected and transmit-only characters through
the first subsequent block terminator or non-
displaying terminator or through the end of display
memory (whichever is encountered first) are trans-
mitted to the host computer as a series of blocks, each
block corresponding to one unprotected field.
Auto TermeJ) = NO
Inh DC2CH)
=
NO
The cursor is NOT repositioned. All unprotected and
transmit-only characters through the first subsequent
block terminator or non-displaying terminator or
through the end of display memory (whichever is en-
countered first) are transmitted to the host computer
as a series of blocks, each block corresponding to one
unprotected field.
Auto Term(J)
=
YES
If the cursor is currently within an unprotected field,
the terminal inserts a non-displaying terminator at
that position and then moves the cursor backward to
the first preceding block terminator or non-displaying
terminator that is not in a protected field (or homes the
cursor if none is found). All unprotected and trans-
mit-only characters from the new cursor position
through the first subsequent block terminator or non-
displaying terminator (whichever is encountered first)
are transmitted to the host computer as a series of
blocks, each block corresponding to one unprotected
field.
If the cursor is NOT currently within an unprotected
field, the terminal merely sounds the bell and
transmits a block terminator to the host computer (or
a
<DC2)
followed by a block terminator if the
DC1/DC2/DC1
handshake is enabled).
ASCII control codes within the fields are transmitted.
Video enhancement escape sequences, alternate character
set escape sequences, and field definition escape sequences
within the fields are NOT transmitted.
After each field (except the final one), the terminal sends a
field separator. After the final field, the terminal sends a
block terminator.

From a program executing in a host computer, you can
trigger a block transfer of data from display memory to the
host computer by issuing the following escape sequence:
<ESC>d
3-10
If the end of display memory is encountered before locating
an unprotected field, the terminal merely sends a block
terminator.
The type of handshaking used is determined as follows:
InhHndShkCG) (ignored)
inhDC2CH)=NO ---)DC1/DC2/DC1
I nh DC2(H) = YES - - -) no hand5hake
MODIFY MODE
Note that modify line and modify all modes are functional
only when the terminal is configured for character mode
operation. Whenever block mode is enabled, the
II1II
key
operates as described for block mode earlier in this table.
The cursor is repositioned as follows:
1. To the logical start-of-text pointer; or
2. To the designated start column (Start Col) ifthere is no
logical start-of-text pointer.
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 the
column at which the transmission began 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
<CR>
(or a
<CR><LF>
if auto line feed mode is enabled); the cursor
remains positioned immediately following the terminator.
The type of handshaking used is determined as follows:
InhHndShkCG) i5 ignored.

With the following three exceptions, the resultant data
transfer is performed as though the
II
key had been
pressed:
1. The cursor is NOT repositioned. The data transfer al-
ways begins at the current cursor positiot,J-.
