Hi! I was able to get the inbuilt GPS in my ASUS Vivo to talk to my legacy GPS software
(Street Atlas 8). I did have to write a little program to access the GPS Location API and convert the Longitude and latitude to NEMA sentences then dump the data to a com port. To complete the magic I found a free null modem
program on the web (there are a number of them like com0com) that connect my program's com port to the legacy program's com port. Worked great.
