Abstract
A bridge device having data monitoring function is disclosed. The bridge device can be made to be an integrated circuit (IC) chip, so as to be disposed on a circuit board with a USB connector and a UART connector, thereby forming a USB to UART converter. When using the USB to UART converter, the USB connector is connected to a host computer, and the UART connector is connected to an electronic device. As such, the bridge device provides the host computer with at least three virtual COM ports, such that the host computer is able to conduct a data transmission with the electronic device through one virtual COM port. Moreover, during the data transmission, the host computer is also able to hear the transmitted data by way of diverting the transmitted data through the other two virtual COM ports.
