Obtain the COM port number mapped to the serial port Background: Recently, due to project requirements, you need to operate the SMS cat. After the SMS cat is inserted into the computer, it will map the COM port based on the current PC status. Here, you need to dynamically obtain the COM port mapped by the SMS
