Well then, if you want to do non-trivial debugging, you'll certainly
hate Insight->OCD Remote->Wiggler clone. As James Lynch points out
in his excellent tutorial, there are days when it just won't work.
To be blunt, it sucks. It isn't worth the aggravation to get it
working; printf works better.
Now, Tom Walsh is more than happy with his high dollar solution
(Abatron BDI2000) and if I were doing this for money, I would buy
the same interface he has. If I could find a distributor in the
US...
And, if the US$ wasn't complete worthless when converted to British
Pounds, I might consider the Rowley CrossConnect package.
