The SAF is the tool used for administering terminals, modems, and other network devices. The top-level SAF program is the Service Access Controller (SAC). The SAC controls port monitors which you administer through the sacadm command. Each port monitor can manage one or more ports.
You administer the services associated with ports through the pmadm command. While services provided through SAC can differ from network to network, SAC and the administrative programs sacadm and pmadm are network independent.
The table below describes the SAF control hierarchy. The sacadm command is used to administer the SAC which controls the ttymon and listen port monitors.
The services of ttymon and listen are in turn controlled by pmadm. One instance of ttymon can service multiple ports and one instance of listen can provide multiple services on a network interface.
