I'll try it out.

Went back to 13 bytes b1 thru b13

serin porta.0,n1200 [qual1,qual2],b1,b2, -- b13

which can be done, right?

even added a long timeout.

n1200,1000,start [qual1 etc

but having problems with it too.

I'm just testing each byte for the right number 1,2,4,8,16 etc

even tried t1200 and pullups and pulldowns -- 22k and no resistor.

I'll get it.
