The cachePort utility caches current instrument service property values for the instrument service running on specified node and port. The values set will then persist through restarts of SIAM or the instrument service. Subsequentinstantiations of the same service on the same node and port will use cached property values rather than the values specified in the associated jar file (or PUCK). Thus it is possible to start a service on a port (e.g. with scanPort), modify one or more property values with the setProperty or setSchedule utility, and then cache the current values with cachePort. The cached property values then persist for each subsequent service instantiation on the specified node and port until the contents of the service jar file (or PUCK) changes, in which case the service is initialized with property values specified in the jar. The properties cache can also be cleared using the -clear option;

Multiple ports may be specified on the command line, e.g.

Options

Option	Description	Values
nodeURL	IP address or host name of SIAM node	e.g. 134.89.88.1, mooring.moos.mbari.org
portName	Name of instrument port (or alias) defined in siamPort.cfg	/dev/ttyS8, COM1, /dev/tty.KeySerial1
-clear	clear the cache and restore property defaults	-
