示例1: kaf_svc
/* Keep-alive service
* If the 8080 detects the 'force reload' bit, it initiates a disk
* boot. IO is reset, but memory is preserved.
*
* If the keep-alive enable bit is set, the -10 updates the keep-alive
* count field every second. The 8080 also checks the word every second.
* If the 8080 finds that the count hasn't changed for 15 consecutive seconds,
* a Keep-Alive Failure is declared. This forces the -10 to execute the
* contents of exec location 71 to collect status and initiate error recovery.
