Source code changes of the file "src/mans/oping.pod" between
liboping-1.9.0.tar.gz and liboping-1.10.0.tar.gz

About: liboping is a C library to generate ICMP echo requests, better known as "ping packets". It can "ping" multiple hosts in parallel using IPv4 or IPv6 transparently. A commandline and a ncurses-based application are included.

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.
