One the occasion when it booted up, I only saw messages coming out every second in NMEA format. But most of the time, I saw messages coming out without a newline flooding the serial terminal. I will paste the message when I get back to that computer. I didn't notice any boot message with firmware version at all. But I will double check. Thanks so much!
