Terminal
Control
A Remote/Local mode
designator
is
maintained
in
non-volatile memory. When you
change
modes
using
the
REMOTE
MODE
key, you also
alter
that
mode
designator
in
non-volatile
memory.
When
you
change
modes
using
the
escape sequences, however,
the
designator
is
not
altered.
After
a
hard
reset
or
turning
off
the
power,
the
terminal
reverts
to
the
mode specified
by
the
remote/local
designator
in
non-volatile memory.
Character/Block Modes
When
the
terminal
is connected on-line to a remote
host
computer,
it
operates
in
either
of
the
following
data
transmission
modes:
•
Character
Mode.
In
this
mode,
data
is
transmitted
a
character
at
a
time
as
it
is
entered
through
the
keyboard. ASCII control codes (such
as
<CR>
and
<LF»
are
transmitted.
• Block Mode.
In
this
mode,
data
is
not
transmitted
at
the
time
it
is
entered
through
the
keyboard.
Instead,
you
transmit
an
entire
block of
data
by
first
typing
the
data
(after
initially
typing
the
data
you
can
move
the
cursor
around
and
edit
the
data
as
desired)
and
then
pressing
the.
key.
When
the
terminal
is
in
Block mode, ASCII control codes (such
as
<CR>
and
<LF
»
are
acted
upon locally
but
are
not
usually
transmitted
with
the
data
block (refer
to
Section 9 for
detailed
information
on Block mode
data
transfers).
From
the
keyboard, you
enable
and
disable Block mode
using
the
BLOCK
MODE
key.
From
a
program
executing
in
a
host
computer, you
enable
and
disable Block mode
using
the
following escape sequences:
ENABLE:
Ec &k1B
DISABLE: Ec &kOB
A Character/Block mode
