Folks,
Just to let you know I got the Sure GPS module:
http://www.sureelectronics.net/goods.php?id=99
working as a source for an NTP server. I added a couple of wire links to
get the PPS signal flowing down the DCD line of the 9-pin RS-232
connector. It seems to be a very sensitive unit, and it worked out of the
box. My hardware patches are documented here:

Tom Van Baak's Web page was an inspiration:

especially the animated GIF!
Now all we need is a comparison between the PPS from this board and true
UTC....
Cheers,
David
