Substate Description
Spool
Inactive
Spooling is not activated. This is either because GemConfigSpool is “0” (disabled) in
which case, spooling will never be active, or because while GemConfigSpool is
enabled (“1”), a RTY error has not occurred. In this state, no messages are sent to the
spool. The Host may define or un-define messages eligible for spooling should the link
go down.
Spool
Active
While GemConfigSpool is enabled (“1”), the Equipment has experienced a
transmission failure (RTY error). Upon entry into this state, the first message sent to
the spool is the GemSpoolingActivated event, assuming that this event is enabled and
that spooling for the particular stream and function have been enabled. This message
will enter the spool even before the message which originally caused the RTY error.
Spool Not Full
- The file containing the spooled messages has not reached its
capacity.
