Communicating With the Safeguard Subsystem
1. Establishing communication with $ZSMP
2. Calling SPI procedures to build the desired message
3. Sending the message
4. Receiving the response to the message
5. Checking for error codes and handling any errors
6. Decoding the response
7. Taking appropriate action and returning to Step 2, if necessary
8. Terminating communication with $ZSMP
If the management application also communicates with a human operator, the
preceding scenario would also incorporate that interchange.
For more information regarding communicating with the Safeguard subsystem, see the
SPI Programming Manual and the SPI Common Extensions Manual.
