* These represent commands that the SAC sends to a port monitor. These
* commands are divided into "classes" for extensibility. Each subsequent
* "class" is a superset of the previous "classes" plus the new commands
* defined within that "class". The header for all commands is identical;
* however, a command may be defined such that an optional data portion may
* be sent in addition to the header. The format of this optional data piece
* is self-defining based on the command. Important note: the first message
* sent by the SAC will always be a class 1 message. The port monitor
* response will indicate the maximum class that it is able to understand.
* Another note is that port monitors should only respond to a message with
* an equivalent class response (i.e. a class 1 command causes a class 1
* response).
