I just checked and there was NO article in the Portable 100 Magazines on
the Club100.org website.

The standard data output of a GPS is NEMA-0183, and is at 4800bps, 8 data,
no parity, 1 stop. Data is output in bursts every 1 second. There is a
newer standard NEMA-2000 that has a transmit speed of 250Kbps, but most all
GPS units should support NEMA-0183.

The standard is well covered here: http://freenmea.net/docs

I am not sure if M100 BASIC alone can keep up with the data bursts and
display useful information at the same time. A machine language driver may
need to handle the data burst reception / parsing task.

Depending on the GPS you are using, there may be several sentences in each
burst. The sentence to start parsing out with is the $--GGA sentence. This
has the useful basic position information.

Regards,

Peter
