+ * The Samsung Kalmia based LTE USB modems have a CDC ACM port for modem control

+ * The stick must first be switched into modem mode by usb_modeswitch

+ * connect the modem using AT commands through the ACM port and then use

+ * sent to and from the modem in a proprietary format discovered after watching
+ * the behavior of the windows driver for the modem.
