@item wrs_pps_control
A tool to switch the PPS output on and off. Usage: ``@t{wrs_pps_control
on}'' switches the PPS output on, and ``@t{wrs_pps_control off}''
pps on}'' switches the PPS output on, and
``@t{wrs_pps_control pps off}''
switches the PPS output off. Switching the output on/off is independent
of the PPSi process, but PPSi switches the PPS output back on when a
link restart is detected and PPSi comes into @t{'TRACK_PHASE'} state.
