Overview of the 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.
