+// TITLE:   DSP2833x Device SCI Echoback.
+//
+// ASSUMPTIONS:
+//
+//    This program requires the DSP2833x header files.
+//    As supplied, this project is configured for "boot to SARAM" operation.
+//
+//    Connect the SCI-A port to a PC via a transciever and cable.
+//    The PC application 'hypterterminal' can be used to view the data
+//    from the SCI and to send information to the SCI.  Characters recieved
+//    by the SCI port are sent back to the host.
+//
+//    As supplied, this project is configured for "boot to SARAM"
+//    operation.  The 2833x Boot Mode table is shown below.
+//    For information on configuring the boot mode of an eZdsp,
+//    please refer to the documentation included with the eZdsp,

+// DESCRIPTION:
+//
+//
+//    This test recieves and echo-backs data through the SCI-A port.
+//
+//    1) Configure hyperterminal:
+//       Use the included hyperterminal configuration file SCI_96.ht.
+//       To load this configuration in hyperterminal: file->open
+//       and then select the SCI_96.ht file.
+//    2) Check the COM port.
+//       The configuration file is currently setup for COM1.
+//       If this is not correct, disconnect Call->Disconnect
+//       Open the File-Properties dialog and select the correct COM port.
+//    3) Connect hyperterminal Call->Call
+//       and then start the 2833x SCI echoback program execution.
+//    4) The program will print out a greeting and then ask you to
+//       enter a character which it will echo back to hyperterminal.
+//
+//    As is, the program configures SCI-A for 9600 baud with
+//    SYSCLKOUT = 150MHz and LSPCLK = 37.5 MHz
+//    SYSCLKOUT = 100MHz and LSPCLK = 25.0 Mhz
+//
+//
+//    Watch Variables:
+//       LoopCount for the number of characters sent
+//       ErrorCount
+//
