Lined up the signal names between the 6 and 10-way connectors, plugged the RS-323 cable into COM1 on my confuzer, ran avrdude, and everything worked great! OK, maybe I had to mess around with it a little bit, but I didn't cuss once. Programmed in about 10 seconds with COM1 set to 4800 buad.
I change the minutes on my clock to some wrong value and it jumps right back to the correct time..... like it's possessed!
Must be the flashing LED on the GPS means it's locked. I was impressed after hooking it up in my basement it even sync'd on the right time.
