Regarding those Tripmates, they won't send GPS data to the computer until you send the magic string "ASTRAL" to the Tripmate. You can either send "ASTRAL" from the M100, or short pins 2 and 3 (TxD and RxD) at either end of the cable. The Tripmate actually expects AND sends the "ASTRAL" string to the M100, thus shorting pins 2 and 3 will send the string back to the Tripmate and jump start it. Douglas
