Thanks, Shanly,
Is it correct to assume that each manufacturer's batch number is unique for
that manufacturer only? IOW, Digicom ('D' = 0x44) could build a roach2 rev 2,
batch 1, board 1 and another manufacturer could also build a roach2 rev 2,
batch 1, board 1 and the only distinction between their serial numbers would be
the 'D' vs the other manufacturer's letter?
Thanks again,
Dave
