		Say Y here if you want to use the auxiliary serial ports provided
		by many modems based on Qualcomm chipsets. These ports often use
		a proprietary protocol called DM and cannot be used for AT- or
		PPP-based communication.

		To compile this driver as a module, choose M here: the
		module will be called moto_modem. If unsure, choose N.
