+ *
+ * This module allows managing the use of the serial ports of TI GSM Evaluation
+ * Boards.
+ * An application may have to send several serial data flows. The board on which
+ * the application is running may have one or several devices. The purpose of
+ * this module is to establish connections between the serial data flows and the
+ * serial devices at runtime, when the application is started.
