Chris --

I've never used array either in picbasic anyway.

You're probably right -- there has to be more to the serin code than what I have shown. ? But all I see with SERIN in the books is how I have it set up.

I do get some action if I use separate byte variables rather than an array --

like [QUAL1,QUAL2],b0,b1,b2,b3,b4 etc

but I really want to use an array -- and to learn how as well.

Everything is setup fine on the breadboard -- I see the data with my scope etc.

Maybe someone can point to the problem, in the mean time I need to study some more on it.
