Theoretically, this script can be tweaked to detect other types of serial port (other than analog modems), but for now, here you have the code that will get you started. To make it easy for the app user, I wrote a Python Script that will locate the COM port associated with the Modem connected with Raspberry Pi. Recently when I was writing an IVR Application using a USB analog modem connected to the Raspberry Pi, I came across the same requirement. Unfortunately, it’s not very straightforward to locate the COM port associated with a Serial or USB device on Linux based operating systems. If you are writing an application that interacts with the analog modem connected to the USB port of the Raspberry Pi you would realize that the first thing that you need in your application is the name of the COM Port.
