Concept of
Subsystem Command
Tree
The
top
of
the
subsystem command
tree is
called the
root command
,or
simply the
root .
T
o
reach
the
low-level
commands
, you
must specify
a particular
path (like
DOS le
directory
path).
After
P
ower
ON or
after *RST
,the
current path
is set
to the
root. The
path
settings
are
changed
as
follows:
Message
T
erminator
A
message terminator
, such
as <
new line
>
character
,
sets
the
current
path
to
the
root.
Colon
(:)
When
a
colon is
placed between
two command
mnemonics,
the
colon
moves
the
current
path down
on level
on the
command tree
.
When
the
colon
is
the rst
character of
a command,
it species
that
the following
command mnemonics
a root-level
command.
Semicolon
(;)
A semicolon
separates two
commands in
the
same
message
without
changing
the
current path.
Common
commands
, such
as *RST
, are
not part
of
any
subsystem.
The
4263B
interprets
then
in
the same
way,
regardless
of
the
current
path
setting.
Figure
5-1
shows
examples
of
how
to use
the
colon
and
semicolon
to
navigate
eciently
through
the
command
tree
.
Figure 5-1. Proper Use of the
Colon and Semicolon
Figure 5-1 shows how character input time can be saved by properly using semicolons
. Sending
the message
:AA:BB:EE; FF; GG
is equivalent to sending the following three messages.
:AA:BB:EE
:AA:BB:FF
:AA:BB:GG
