Abstract: On most development systems, a reasonably secure system
is desired. RSX-11 is a fine tool for developing code
for industrial applications, but its security regarding
unattended terminals is not satisfactory. It is not
desirable for anyone to be able to walk up to a
terminal, if the terminal is privledged (as most are on
development systems) delete any and all files he wishes.
 
This monitor addresses this problem. It examines system
terminal driver data structures looking for logged-in
terminals, and scans the active task list looking for
the "owning terminal" for all active tasks. It gives
idle terminals first, second and final warnings, and
logs all forced logouts on the system console. The
monitor serves all TT: devices on the system, and can be
built to support DECnet HT: devices. VT100 support can
be included. All time parameters are user-selectable,
including an optional 'hibernation' period.
 
Notes: This version corrects deficiencies in previous releases
relating to logout of the last active terminal on the
system and occasional unpredictable behavior. Program
makes use of new directives in later releases of RSX and
maps Executive directly.
