    Header file so C routines can safely call routines in the
    file Serialio.s

    Note: although AvrX is processor independent, Serialio.s is not.
    You MUST compile this file for the particular CPU being used as
    GCC no longer places interrupt vectors at link time.

    09/18/2005 - It is recommended that these routines not be used for
    user code.  See the sample AvrXIo for more generic, flexible serial
    I/O routines.
