I want to use Device::Modem to connect to my Serial Modem. The problem i am facing is to find which port my modem is connected to. I am using Windows XP and found no way to check which port my Modem is connected to. Since this is going to be performed on many systems, it is practically impossible to go to each system and find that manually using Device Manager. I tried to query all Com ports using Device::Modem, but I am getting error: The system cannot find the file specified. can't open device: \\.\COM4 Any help will be highly appreciated!
