Thanks for all the good ideas, everyone!  I'll give some of them
a try tomorrow- if one of them is easier than my method, I'll
mention it.

In the meantime, what I finally did was grab a copy of Scilab,
save the data into a binary output file from FireSpy, grab the
data from the file one byte at a time and load it into a matrix,
then use SciLab's built-in grayplot function to plot the values.

The plotting process is slow, but it works.  Perfection of the
image isn't necessary; I just needed to know whether it was
getting garbled at the host end or the device end.
