I have a hack that grabs everything and writes each line and a time stamp to a file per day. http://users.megapathdsl.net/~hmurray/time-nuts/Arctic/code/AAA-README http://users.megapathdsl.net/~hmurray/time-nuts/Arctic/code/grab-nmea.py I'd use two copies of it - one for the TICC and another for the NMEA. You can merge them on post processing. The time stamp is the end of line. If you know the baud rate and number of stop bits, you can calculate the start time. Again, post processing. -- These are my opinions. I hate spam.
