Thanks for the help. I got on aximsite and found out that it was a timing issue. With my combination of software, I need to plug in the gps at exactly the right time. Too early . . . locks up. Too late . . . "no information coming from serial port" message. It seems there is about a 1/2 second window to get it done properly. I'll be testing it some more this weekend to make sure there are no bugs. Thanks again.
