Summary: in the continuing serial...  Can you DMA to the serial port?


Is it possible to have a block of data shipped to the serial port in a
   similar manner as for the audio?  (where you specify a big block of ram,
   set pointers and bytes/second, and the hardware does the rest).
If so, will the memory fetches steal any processor time?
And then how about the reverse- serial directly into memory?  (let's say
   given that data is coming in nonstop at whatever bit rate).
