3 * SERIALSWITCH.C
4 *
5 * This module allows managing the use of the serial ports of TI GSM Evaluation
6 * Boards.
7 * An application may have to send several serial data flows. The board on which
8 * the application is running may have one or several devices. The purpose of
9 * this module is to establish connections between the serial data flows and the
10 * serial devices at runtime, when the application is started.
