I can see two potential problems - except I don't have manuals, so I'm
sure to make a mistake, which someone will then correct. Oh well, no
one else has poined these out, so...

1) I don't see a starting point specified for OurStart(). Maybe BLINK
defaults to someting intelligent, but I'd be leery of it.

2) In starting cpr, you should specify that it not run the startup code
(-s switch, I believe). I wouldn't be surprised if it's getting
confused and hanging.
