None
Initiates and aborts specific analyzer functions.
Set this to 0 before and after any other number - the analyzer responds to a change
in this variable's value. Leave it on the desired value for a second before changing it
back to 0. This variable is used by other modules on the network to initiate actions in
the analyzer, and may also be used by PC programs to do the same thing.
