Service Access Facility

The SAF is the tool used for administering terminals, modems, and other network devices. In particular, SAF enables you to set up:

• ttymon and listen port monitors (using the sacadm command)

• ttymon port monitor services (using the pmadm and ttyadm commands)

• listen port monitor services (using the pmadm and nlsadmin commands)

• And troubleshoot tty devices

• And troubleshoot incoming network requests for printing service

• And troubleshoot the Service Access Controller (using the sacadm command)

The SAF is an open-systems solution that controls access to system and network resources through tty devices and local-area networks (LANs). SAF is not a program. It is a hierarchy of background processes and administrative commands.
