Terminal Control
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]
(respectively),
and
the'
and
~
keys
are
ignored.
From
the
keyboard, you
enable
and
disable Caps Lock mode
using
the
Caps
Loc
k field of
the
Terminal Configuration
menu
described
in
Section 3.
From
a
program
executing
in
a host computer, you enable
and
disable Caps Lock mode
using
the
following escape sequences:
ENABLE:
Ec
&k1C
DISABLE: Ec
&kOC
At
any
given
time
the
current
state
(enabled/disabled) of Caps Lock mode
is
reflected
in
the
Caps
Loc
k field of
the
terminal
configuration menu. When you
enable
or
disable
the
mode by
altering
the
menu
field from
the
keyboard
and
then
pressing
the
SAVE
CONF
IG key, you
alter
both
the
active
and
non-volatile memory versions of
that
field. When you
enable
or disable
the
mode
using
the
escape sequence, however, you only change
the
active
value
of
the
Caps
Lock
field
in
the
terminal
configuration menu.
After
a
hard
reset
or
turning
off
the
power,
the
terminal
reverts
to
the
mode specified by
the
Caps
Lock
field
in
the
terminal
configuration
menu
in
non-volatile memory.
Format Mode
The
terminal
includes a
Format
mode
in
which elaborate, custom-designed forms
containing
protected
and
unprotected fields can be displayed on
the
screen
and
used for
data
entry.
When
Format
mode is enabled,
the
terminal
operator
may
only
enter
data
into unprotected
fields.
If
the
operator
positions
the
cursor
in
a protected
area
and
then
attempts
to
type
data,
the
cursor
automatically
moves to
the
start
of
the
next
subsequent
unprotected fIeld before
the
terminal
accepts
the
data.
From
the
keyboard, you
enable
and
disable
Format
mode
using
the
FORMAT
MODE
function
key, which is available
in
the
Define Fields
set
offunction keys.
From
a
program
executing
in
a
host
computer, you enable
and
disable
Format
mode
using
the
following escape sequences:
ENABLE:
Ec W
DISABLE:
Ec
X
Once
Format
mode is enabled,
it
remains
enabled
until
explicitly disabled,
until
a
hard
reset
is performed,
or
until
the
power
is
turned
off
