DCMT VARY LINE Usage

MASTER/SLAVE Binary Synchronous Lines

The MASTER/SLAVE parameters change the relationship between two points on a binary synchronous point-to-point line. You use this command to avoid contention problems in an environment where a single, bisynchronous line must carry messages in both directions.

By default, DC/UCF is the slave when it is connected to a non-CA IDMS system. However, when two DC/UCF systems are connected to each other, you need to define one side the master and the other side as the slave.
