Service Access Facility

The SAF is the tool used for administering terminals, modems, and other network devices.

In particular, the SAF enables you to set up the following:

• ttymon and listen port monitors by using the sacadm command

• ttymon port monitor services by using the pmadm and ttyadm commands

• listen port monitor services by using the pmadm and nlsadmin commands

• Troubleshoot tty devices

• Troubleshoot incoming network requests for printing service

• Troubleshoot the Service Access Controller by 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). The SAF is not a program, but a hierarchy of background processes and administrative commands.
