Example Query ROUTE:PFAil:OPEN? (@101,205);

The inclusion of a question mark causes a readback of the power up state of the requested channels as a list of 1s and 0s separated by commas.

A 1 means the channel is in the PFA:OPEN list.

A 0 means that it is not.

When querying the PFAIL state, the PFA:CLOS list must be checked as well to determine whether the power up state for a given channel is programmed at all.

If a relay is in neither the PFAil:OPEN or PFAil:CLOS lists, its power up state is determined by the last save stored to EEROM for that relay.

The query form is not available when using a path name, due to the potential for confusion between the first group and the second in the path.
