 I think Allison meant that the 8530 had the DRQ/DACK
signals needed to
make it easily work with a DMA controller.  Most simpler UART chips
didn't have those. 
No Eric, when I said it had DMA I ment the bus master and the data 
counters.  Sheesh, I have disks near as old as me then drop more bits
but munging info like that is a major brain fart.  Oh well least I 
have the data books and the parts to correct myself.

Oh, along the way the 85C30 was a far better part.
