1. This is paragraph 1. It should
be the first one.
2. This is paragraph 2. It should
be the second one.
4. This is paragraph 4. It should
be the last one.
b. Position the cursor in the first line of paragraph 1.
c. Enable memory lock mode.
d. Use the" key until the first line of paragraph 4 is in
the same line as the cursor.
e. Disable memory lock mode and home the cursor. The
display should appear as follows:
1. This is paragraph 1. It should
be the first one.
2. This is paragraph 2. It should
be the second one.
3. This is paragraph 3. It should
be the third one.
4. This is paragraph 4. It should
be the last one.
From the keyboard, you enable and disable memory lock
mode using the
"MEMORY LOCK"
key.
From a program executing in a host computer, you enable
and disable memory lock mode using the following escape
sequences:
ENABLE:
<ESC> 1
DISABLE:
<ESC>m
Once enabled, memory lock mode remains enabled until
explicitly disabled, until a hard reset is performed, or until
the power is turned off.
.
Display Functions Mode
When display functions mode is enabled the terminal
operates as follows:
• In local mode, it displays ASCII control codes and escape
sequences but does not execute them. For example, if you
press theD key the terminal displays
<ESC>D
on the
screen but does not perform the "cursor left" function.
• In remote mode, it transmits ASCII control codes and
escape sequences but does not execute them locally. For
example, if you press the
II
key the terminal trans-
mits an
<ESC>S
but does not perform the "roll up" function.
Iflocal echo is enabled
(ON),
then the
<ESC>S
is also dis-
played on the screen.
There are two exceptions to the above descriptions:
1. An
<ESC>Z ,
which disables display functions mode, is
executed in addition to being transmitted and/or dis-
played.
2. A
<CR>,
which is both displayed and executed. Note that
the
<CR)
is always executed as a carriage return
3-4
followed by a line feed. The <
LF
> code is only displayed,
however, when auto line feed mode is enabled.
C
From the keyboard, you enable and disable display func-
tions mode using the
"DISPLAY FUNCTNS"
key.
From a program executing in a host computer, you enable
and disable display functions mode using the following
escape sequences:
ENABLE:
<ESC>Y
DISABLE:
<ESC>Z
Once enabled, display functions mode remains enabled
until explicitly disabled, until a soft or hard reset is per-
formed, or until the power is turned off.
Caps Mode
When caps mode is enabled, all unshifted alphabetic keys
generate uppercase letters and all shifted alphabetic keys
generate lowercase letters. This mode is used primarily as
a typing convenience and only affects the 26 alphabetic
keys.
From the keyboard, you enable and disable caps mode
using the
III
key. This key alternately enables and
disables caps mode.
From a program executing in a host computer, you enable
(
and disable caps mode using the following escape se-
quences:
ENABLE:
<ESC>& k1P
DISABLE:
<ESC>& k OP
Once enabled, caps mode remains enabled until explicitly
disabled, until a hard reset is performed, or until the power
is turned off.
Caps mode, when enabled, has no effect upon data received
over a data comm line.
Caps Lock Mode
When caps lock mode is enabled, the terminal generates
only Teletype-compatible codes: uppercase ASCII (OO-5F,
hex) and
DEL
(7F, hex). Unshifted alphabetic keys
(a-z)
generate the codes for their uppercase equivalents, the {,
I,
and} keys generate the codes for [, \, and J(respectively),
and the - and ' keys are ignored.
From the keyboard, you enable and disable caps lock mode
using the"
Cap
!I
Lac k "
field of the terminal configuration
menu described in Section II, Configuring the Terminal, of
this manual.
From a program executing in a host computer, you enable
and disable caps lock mode using the following escape
sequences:
ENABLE:
<ESC>lrk1C
DISABLE:
<ESC>&kOC
