Bridge module, uart expansion device, and method of showing customized serial port name

A UART expansion device having a function of being changed a serial port name thereof to be customized, comprising:

• a circuit board;
• a signal interface, being disposed on the circuit board;
• at least one UART interface, being disposed on the circuit board;
• and
• a bridge module, being disposed on the circuit board, and comprising a bridge electronic chip and a memory coupled to the bridge electronic chip;
• wherein the bridge electronic chip is coupled between the signal interface and the UART interface, and the memory storing a customized serial port name;
• wherein the bridge electronic chip is configured so as to conduct:
• reading out, in case of the signal interface being connected to a host electronic device that has been installed with a driver of the UART expansion device, the customized serial port name from the memory;
• transmitting, after integrating the customized serial port name in a device descriptor, the device descriptor to the host electronic device;
• transmitting, in case of the UART interface being in connection with an electronic device, a first UART signal that is converted from a first signal received from the signal interface to the electronic device;
• and
• transmitting, in case of the electronic device transmitting a second UART signal to the UART interface, a second signal that is converted from the second UART signal to the host electronic device through the signal interface.

A method of showing customized serial port name, comprising:

• further integrating, a memory into a UART expansion device that comprising a signal interface, at least one UART interface and a bridge electronic chip coupled between the signal interface and the at least one UART interface;
• making, the memory be coupled to the bridge electronic chip;
• installing, after the signal interface being connected to a host electronic device, a driver of the UART expansion device in the host electronic device;
• and
• configurating the bridge electronic chip to conduct:
• programming, after receiving a writing data including a customized serial port name from the host electronic device, the writing data into the memory;
• reading out, in case of the memory storing customized serial port name as well as the signal interface being connected the host electronic device, the customized serial port name from the memory;
• and
• transmitting, after integrating the customized serial port name in a device descriptor, the device descriptor to the host electronic device.
