<p>A device and method for breaking download channel of a Hand-held terminal. The device includes: a connection/disconnection unit (308) which comprises a fuse module (308-2) and a fusing module (308-4) is set between a download connection point (302) and a microprocessor (306); when download is not needed by the hand-held terminal, through the download connection point provides the fusing module (308-4) with a power level signal, and utilizes switch characteristics of a dynatron or a MOSFET in the fusing module (308-4), the connection/disconnection unit (308) controls connection or disconnection of the download channel between the download connection point (302) and the microprocessor (306), thus prevents generation of new the download channel.</p> |
