enableButtonSig()
Calling enableButtonSig() causes the signal SIGINT to be sent to the
registering process when the recessed button is pressed for less than two
seconds.
Sending a SIGINT to a process when the recessed button is pressed is done so
that the application can implement a setup/configuration mode. The application
receiving the SIGINT can drive the GUI as desired.
NOTE
If the user presses the recessed button for longer than two seconds, the normal
system mode password display will be called.
