-\section{Enabling job control}
-In this lab, we are going to run a buggy program that keeps hanging
-and crashing.  Because of this, we are going to need job control, in
-particular \code{[Ctrl] [C]} allowing to interrupt a running program.
-At boot time, you probably noticed that warning that job control was
-turned off:
-/bin/sh: can't access tty; job control turned off
-This happens when the shell is started in the console. The system
-console cannot be used as a controlling terminal.
-The fix is to start this shell in ttyS0 (the debug serial port on
-the sama5d3 Xplained board) by modifying the \code{/etc/inittab} file:
-which implied the use of the system console device by
-to tell the \code{init} program to start the shell on \code{/dev/ttyS0}
-Now reboot. You should no longer see the \code{Job control turned off}
-warning, and should be able to use \code{[Ctrl] [C]}.
