The ordering of the Logic Elements is as follows: (The term "Event Code" includes
"Negated Event Code")
Event Terms:
First element of term can be "(", a space, or an Event code
If a space there are no Events, but there may be Actions. (see below)
If "(", the next element must be an Event code.
If an Event code, if numerics are required for a specific code, they will
be next.
After an Event code, with its numerics, there may or may not be a ")".
Next will be either a connector or a space.
If a space, an Action code will follow.
If a connector, an Event code will follow.
Action Terms:
Up to 5 Action codes make up the action terms. Each code will be
followed by a numeric if it is required. Note there are no connectors
passed with the Actions, as all Actions are ANDed together.
The logic statement response ends with an 0x03.
