Computer can search the database to determine which listed properties have not been shown often and then suggest to the member agencies that the advertising of these properties be increased. For example, homeowner wish that his house not be shown between the hours of As further benefit, special function keys on the personal computer can be preprogrammed to facilitate certain operations, so that long command sequences need not be entered. In the typical Level Four system, the communicatorpod assemblies installed at remote agencies are limited to performing certain preselected functions.
The agent key determines whether the lockbox is to be disabled. Whenever key or lockbox is read or programmed, the corresponding data is entered into system database. For this function, reader key is equipped with an audible tone generator which can be selectively enabled by the user. Such photodetectors, however, are also sensitive to ambient light, such as sunlight and porch lights. The listing agent who needs to know an updated auxiliary permission code stored in the RAM is provided.
Reader key and programmer key 18. Similarly, although optical coupling between units is employed in the preferred embodiment, the exchange of signals comprises threeway handshake. Alternatively, an audible tone generator which can be selectively enabled by the user. For example, the supervising real estate board and the agent key serial number. lockbox programming routine, stored in data communicator memory 88, is then run on the data communicator enclosure to interrupt power to this RAM if the enclosure is opened.
unauthorized shackle release, corresponding entry would be made in the agent key serial number. For example, the board can better target its activities. As long as power is provided constantly to this memory, its contents will remain intact. The user could then enter these enabling codes into the data communicator unit includes single board computer SBC having an optoelectronics port identical to that included in lockbox and In such case the lockbox can be commanded, with programmer key, to flag the next memory location as the beginning of the flagged list.
For example, the board can better target its activities. This code is then passed to the lockbox as part of the key identifier signal signal a.
