This project is to use a Pro Mini to manage 3 serial ports. I'm planning to use 3 FTDI/USB BOB's for the inputs. Since the Pro Mini needs an FTDI/USB port for uploading and IDE comms, I'd like to be able to share one of them for upload and serial debug comms.
It seems a huge waste to put a 4th port on just for the development work - I'm looking for some info on how to switch a given FTDI from "development mode" to "application mode".
During development I could dedicate one port to debug I/O and then work on the other two - and shift around as needed.
