 *  ======== siotest1.c ========
 *  In this program a task reads data from a DGN sine device and prints the
 *  contents of the data buffers to a log buffer. The data exchange between
 *  the task and the device is done in a device independent fashion using the
 *  SIO module APIs.
 *
 *  The stream in this example follows the SIO_STANDARD streaming model and is
 *  created using the DSP/BIOS Configuration Tool.
