config
You
can
change
some of
the
parameter
settings
in
the
terminal
configuration
menu
programmatically
by
using
escape sequences.
Normally
these
escape sequences
are
issued
from a
program
executing
in
a
host
computer
but
they
may
also be
entered
through
the
keyboard.
Lock/Unlock Configuration Menus
U
sing
an
escape sequence,
you
can
"lock"
the
current
configuration
menus
(terminal
config,
port

and
port
2 config)
so
that
the
menu
can
neither
be accessed from
the
keyboard
nor
altered
programmatically.
Any
attempt
to
access a locked
menu
from
the
keyboard
will
result
in
the
"FUNCTI
ON
LOCKED"
error
message;
the
terminal
operator
clears
the
message
by
pressing
l1li.
Note
that
when
the

menus
are
locked,
the

use
the
following escape sequence:
<ESC>&g 1 L

The

and

alter
the
particular
parameter
in
the
menu,
and
the
new
setting
takes
effect immediately,
but
they
do
NOT
alter
the

If
a

is

on

screen
when
the
escape
sequence
is
received,
the
sequence is executed
after
the
menu
has
been
removed (by
the
operator) from
the
screen.
