More detailed information about the syntax can be found in the Instruc-
tions for Use of the instrument from which the status messages should
be transmitted.
With the LEARN function transmitted data (= character strings) can be
taken over interactively (see section 4.3.4).

arbitrary 14 bit pattern
The
CTL:Rm
command controls external instruments via the remote in-
terface. It causes the setting of defined line states or the sending of
pulses via the 14 remote output lines.
Predefined bit patterns are supported which can be selected by short
names (e.g.
'INIT 732'
or
'ZERO 1'
).
Setting particular bit patterns allows flexible control of connected in-
struments.
Here the following is valid:
0
= line inactive
1
= line active
∗
= do not change line state
Example:
***000*******1
= Output line 0 active
= start/stop time program at 732/1
For details about the remote interface, see section 5.1.
