Bc2000 (for the BCF2000 & BCR2000)

Cheers Royce..

I tried your suggestion in script - but no joy.
So i tried all the different  valn.n options in BCmanager.

Finally... the reverse of the data bytes
$E0 val7.13 val0.6 seems to work. 
Perhaps alphaports documentation had a slight error.

Thanks to all.
I'll tweek the speed settings this weekend and upload the file with some notes.
