 *   end of the powerline;
 *
 *   the default address is 00:B0:52:00:00:01; omitting the address
 *   will automatically address the local device; some options will
 *   cancel themselves if this makes no sense;
 *
 *   the default interface is eth1 because most people use eth0 as
 *   their principle network connection; you can specify another
 *   interface with -i or define environment string PLC to make
