+# Some chips support alarms with beep warnings. When an alarm is triggered
+# you can be warned by a beeping signal through your computer speaker. It
+# is possible to enable beeps for all alarms on a chip using the following 
+# line:
+#
+# 	set beep_enable 1
+#
+# or disable them using:
+#
+# 	set beep_enable 0
