+Audible bell. Print a ASCII BEL character (\a or 0x07) when a packet
+is received before the timeout occurs. This can be useful in order to
+monitory hosts' connectivity without looking physically at the
+console, for example to trace network cables (start audible beep,
+disconnect cable N: if beep stops, the cable was in use) or to tell
+when a host returns from a reboot.
+
+This relies on the terminal bell to be functional. To enable the
+terminal bell, use the following instructions.
