So i made simple 'on the fly' gps protocol translator. It is driver for COM port. After installation it creates new COM port to which your program should connect. Configuration included inside cab creates COM6 and reads from COM7 (my TG01 configuration). After installation you should set proper values for your system in registry key HKLM\Drivers\Builtin\WNROFIX. The value 'SourcePort' contains number of port where you have original gps source, the value 'Index' is number of new port. It should be 'free' number to not collide with existing COM ports....

Hello,
I have found this WNRO topic a little late, but Thank you very much for your work

I have an Asus A696 for about 15 years now.
It seems to be alive again with this driver.

Also, I have had to switch back the SIRF3 chip into "SIRF" Mode with SirfTech (I have had set it in "NMEA" protocol since many years, and the driver was not working).

For those who would like to set their SIRF3 chip, I have attached the software and the .reg file for A696 with COM9 for the Index port value.
BUT be warning: This can brick the chip ! And there is no way to fix that.
