The
CTL:Rm
command controls external instruments via the remote
interface. 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
732/819'
or
'ZERO 1'
).
Here the following is valid:
0
= line inactive
1
= line active
∗ = do not change line state
Example:
*************1
= Output line 0 active
= advances 797 VA Computrace
For details about the remote interface, see section 3.2.

command data (= character string) can be sent to
instruments connected via the serial RS232 interface.
