The bsmunconv script removes the line in the /etc/system file that allows users to abort the system with the Stop-A keyboard sequence. If you want to continue to prevent users from aborting the system with the Stop-A keyboard sequence after you run the bsmunconv script, you must reenter into the /etc/system file the line that reads: set abort_enable=0.
