I have a GSM modem connected via USB. The modem creates 2 serial ports. The first is automatically attached to the modem, the second shows in Device Manager as "HUAWEI Mobile Connect - 3G PC UI Interface (COM6)" The second port is used to get vital information from the modem, such as signal quality; to send and receive text messages; and a whole host of other functions. I am writing an application that will wrap up some of the features provided by the second port. What I need is a sure fire method of identifying which COM port is the spare one. Iterating the ports and checking a response to
