409 | * - dev->name or dev->bus->name must contain "modem" substring; | |
410 | * - device must have only one IO region (8 byte long) with base address | |
411 | * 0x2e8, 0x3e8, 0x2f8 or 0x3f8. | |

413 | * Such detection looks very ugly, but can detect at least some of numerous | |
414 | * PnP modems, alternatively we must hardcode all modems in pnp_devices[] | |
