Motorola phones use "interesting" setup. There's qmi and "normal" (but very buggy) AT interface on them. Unfortunately that uses USB and uses too much power (which is a problem on phone). Plus there's /dev/motmdm1, motmdm3 and motmdm9, multiplexed over serial line. It uses subset of AT commands (good) with slightly modified protocol... it says ":OK" instead of "OK" and puts ~ before unsolicited messages. Other major difference is that commands need to be sent to the right device. It seems motmdm1 is for status and call control, and motmdm9 is for incoming sms. I guess that right way to do this is to introduce drivers/motorolamodem (or can we just have drivers/motorola?).
