cursor
control key, such
as

or
any
of

of

(at
the

only.

computer
only.

executed
in
the

This
means
that
if
the

is
in
Local mode,
the
contents
of
the

are
executed locally
(displayable
characters
are
sent
to
the
display).
If
the

is
disabled (configuration
item

the
contents
of
the

are
trans-
mitted
to
the
host
computer.
If
the
terminal
is
in
Remote mode
and
local echo
is
enabled
(on),
the
contents
of
the

are
both
transmitted
to
the
host
computer
and
executed
locally.
If
the
terminal
is
in
Block mode,
the
contents
of
the
key
are
executed locally.
