List of Error Messages
            A filter must have at least one coefficient specified.
702 Load/Store Error; Cannot create a Modulation with less than one bit per
     symbol.
            A modulation must have at least two states specified.
702 Load/Store Error; Cannot create a shape with less than 2 points.
            Burst shape files must have two or more points for both the rise
            and the fall shape specification.
702 Load/Store Error; File: '{name}'. A FIR selected for a Real-Time
     Modulation filter must have an OSR of at least 2, cannot have more
     than {value} symbols, and must be real. You may have specified an
     incorrect over-sample ratio in the filter table  editor.
            The selected User FIR does not have the correct value and range of
            parameters expected for a User FIR for a Real-Time Modulation
            filter.
702 Load/Store Error; File: '{name}'. A FIR selected for an internal
     equalization filter must have an OSR of 1, must have from 2 to 256
     taps and must have an equal number of real and imaginary coefficients
     if the FIR is complex. The previous equalization filter is still in
     effect.
            The selected User FIR does not have the correct value and range of
            parameters expected for a User FIR for an internal equalization
            filter.
702 Load/Store Error; Invalid modulation file.
