 * SERIALSWITCH.H
 *
 * 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.
