This is a writable flag controlling whether NM*SysMgr receives OPCOM TAPES-class messages, taking effect at the next process start-up. An administrator enables this to capture operator notifications about tape drive events, such as a tape mount request or end-of-tape condition. For example, enabling sCfgOpcomTapes on a system doing nightly tape backups would let the administrator see tape-related operator messages forwarded as traps.
