Total Newb! I need to convert a serial stream to a .csv on the fly? Any ideads on whe
 

Data flows in over serial and I need to create a .csv from it every 5 minutes for the rest of time......please help. I have access to tools, O/S's, hardware, etc.....just not sure where to begin.

Um ... create a pipe from serial reader to your process and use cron? But if you want stability and guarantees you got all the data, a db would probably be better.
