What is the device hooked up to on the machine itself? ModemManager does not usually auto-probe various platform drivers, because it cannot know that a modem is connected as these are not USB/PCI/etc and either do not provide device identifiers, or the device is a generic serial adapter which doesn't necessarily indicate a modem either (eg, it could have a UPS attached or something). So generally for these devices, if you have one you know what you are doing, and you can add a whitelist entry for it quite easily with udev rules. But let's confirm the details first.
