You probably already have this info but if not perhaps it would help a little.

This is a nice summary of NMEA protocol:

And the Trimble Lassen documentation has a nice description of TSIP and TAIP:

On the diagnostics, if not on a separate screen then even some corner pixels coded or character variations could be made to work for # satellites etc.

I originally started this thread a while back toward this end:

Still struggling with Python. Does it actually find the route.html file or what? Perhaps my Python installation is kaput. I just get:

NameError: parse....

My autoHijack Python script seems to run ok, however.

Thanks,
