KPPPLoad is a network load monitor.
It displays the current transmit rate and receive rate, the
total bytes transmitted and received, an xload-style graph
of transmit and receive rates, and the connect time in the
title bar.
It can automatically run a user-specified command to redial
the PPP link when it is disconnected, and can execute a
user-specified command periodically, but only when the PPP
link is up.
