if auto line feed mode is enabled); the cursor
remains positioned immediately following the terminator.
The type of handshaking used is determined as follows:
InhHndShk(G) i5 ignored.
InhDC2(H)=l'Io
--->DC1/DC2/DC1
I nh DC2(H) = YES - - -) no hand5hake
BLOCK LINE MODE, FORMAT MODE
Auto Term(J) = 1'10
If the cursor is currently within an unprotected field,
all characters from the current cursor position
through the next subsequent block terminator or non-
displaying terminator or through the end of the field
(whichever is encountered first) are transmitted to the
host computer as a block. Otherwise the terminal
searches for the next subsequent unprotected field and
transmits data from that field.
AutoTerm(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 within a protected field (or
homes the cursor ifnone is found). All unprotected and
transmit-only characters from the new cursor position
through the next subsequent block terminator or non-
displaying terminator or through the end of the first
unprotected field (whichever is encountered first) are
transmitted to the host computer as a block.
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 field are transmitted.
Video enhancement escape sequences, alternate character
set escape sequences, and field definition escape sequences
within the field are NOT transmitted.
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 positioned at 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.
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) (ignored)
I nh DC2(H) = 1'10 - - - > DC1 IDC2/DC1
I nh DC2(H) = YES - - - > no hand5hake
BLOCK PAGE MODE
Auto Term(J) = 1'10
Inh DC2(H) = YES
The cursor is repositioned to the "home up" position.
All characters through the first subsequent block ter-
minator or non-displaying terminator or through the
end of display memory (whichever is encountered
first) are transmitted to the host computer as a series
of blocks, each block corresponding to one line in dis-
play memory.
Auto Term(J)
=
1'10
Inh DC2(H) = 1'10
The cursor is NOT repositioned. All 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 line in display memory.
Auto 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 first subsequent block terminator or non-
displaying terminator (whichever is encountered first)
are then transmitted to the host computer as a series of
blocks, each block corresponding to one line in display
memory.
ASCII control codes, video enhancement escape sequences,
alternate character set escape sequences, and field
definition escape sequences are all transmitted if
encountered.
After each line (except the final one) the terminal sends a
<CR><LF>.
If the operation is terminated by encountering
the end of display memory, then the terminal sends a
<CR><LF>
followed by a block terminator after the last line.
If the operation is terminated by encountering a block
terminator or a non-displaying terminator, the terminal
sends only a block terminator after the last line.
If there is no data to be transmitted the terminal sends only
a block terminator.
The type of handshaking used is determined as follows:
InhHndShk(G) (ignored)
InhDC2(H)=l'Io
---)DC1/DC2/DC1
Inh DC2(H) = YES - - -> no hand5hake
