On thing you might want to set if it isn't already is AT&B1. This tells the modem to use a fixed serial rate, not one that's adjustable based on connection. Since you showed that mgetty was able to communicate with the modem for setting it up it's a little weird that when rings come in it gets that garbage. Oh, the [0d] [0a] are CR and LF, respectively. BTW, why are you setting the port speed to 38400? Why not just set to 115200?
