TTY management

The minimum SL, maximum SL, and TL for tty devices are defined in the ttys database in the /etc/login.cfg file. Refer to chsec command for more information.

The effective SL of the user logging in over the TTY port should be within the range defined for this port in this file. If a TL other than NOTL is specified for the TTY port, then the effective TL of the user must be the same as the specified TL.
