Here's another thing I just noticed:

s_seq is now an array (we used to initialize s_seq to 0)

We only save the DCU sequence values if changing a channel

But always write it.  The old code did this too, the only difference
was we explicitly initialized the s_seq[0] to 0.  Since it's an array,
gcc won't warn about it but s_seq[] probably has random crap in it.
