The logic analyzer and serial passthrough seem to be implemented on-chip
though, not with scripts. Makes sense since they require fast response.

It is a bit verbose, but otherwise I've found it quite straightforward, at
least the part I've looked at (only initialization and a few simple
scripts). Most of the beef seems to be in the .dat file, and using
that is mostly figuring out in which order to run the standard set of
scripts. (Just an impression, I haven't got it working yet..)
Jeff, Xiaofan, any comments on the source of pk2cmd? What did you add?
