Hello
msparish, great to hear that you may get a new P4 helping in the search.
Just set SetiDriver to AUTO TRANSMIT. Be sure to hit that SAVE CONFIG button to save the change.
What will happen is upon completion of a Work Unit, SetiDriver will try to send in that Work Unit and any others that have not yet been transmitted up to that time. If it fails to find an internet connection (make contact) it will time out and wait for one hour.
Eventually, when a Work Unit gets completed AND your sister happens to be online, all completed WUs will be sent in and new ones will be downloaded.
So as
RaySun2Be just suggested, you need to make sure a sizable number of Work Units are being cached.
Since her computer can do approximately 8 WUs @ day, I'd suggest you cache between 80 - 100 Work Units.
And don't forget to tell her to keep her computer running even if she is not on the internet.
