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). David Carter
