ABSRTA.CT - NOTAIL.MAC Abstract for DECUS: 23-Oct-88 Tailgating is the name commonly given to what happens when a modem data path is broken before the job using it has logged off, and the next call is connected to that still active session of the prior user. On a busy TSX-Plus system, this can be a problem as the same time value (TIMOUT) which governs how long a job will be held active after the data carrier has been lost also determines the time allowed for a caller to first connect, type two returns and initialize the line. Thus, setting TIMOUT small enough to prevent tailgating means it's not likely anyone will be able to log on a phone line either. This little program, running as a detached job, checks desginated lines every 0.5 second and kills any that may still be logged on without dcd held true. TSX-Plus V6.3 or above is required as recent prior versions only allow the kill emt to bomb detached jobs. [Editor's note: last sentence not true: only awkward to do! See TSCLIB KILL.MAC for details.]
