摘要

A portable computer is described that contains a circuit for receiving pages and performing security functions based on the received page. Once a page has been received by the portable computer, the computer's hard drive can be automatically reformatted, or the portable computer can be prevented from booting. In addition, the portable computer can be programmed to use a modem to automatically dial a security center and transmit security information such as the Caller ID Tag of the current telephone number.
