Description of Arguments
Command only.
Resets internal pointer to allow RNS? queries to start at the
beginning of the statistics log.
Command only.
Forces the unit to toggle the Unit Fail relay to the "fail" state for
approx 500ms. If the unit is a 1:1 pair, and it is currently the 'On-
Line' unit, this will force a switchover, so the unit will then be in
'Standby' mode. The command is always executed by the unit,
regardless of whether it is stand-alone, in a 1:1 pair, or part of a 1:N
system.
This command takes no arguments.
