This is for a base station wind instrument which I'm putting together for a sailing club.
They have the NMEA instrument and have asked that I can put nice pretty graphs of wind
speed and direction up on their website. I'm thinking of just writing some code myself to
take the input and create a text file with it and have that FTP'd to their webspace and
run CGI scripts to graph it.

This might make it a bit clearer!
I hope

You can find the data structure of NMEA from many places in the webb.
Just do your own coding for reading the serial port. After saving the
log into a file, you can use tools like gnuplot to automatically make
a graph from the last N hours in the format you like. With gnuplot,
you can make many formats from a command line.

You might find this interesting.

I have no knowledge of the product. It was pointed out to me by a
prospective customer who wants to use it to send NMEA data directly to
my program over ethernet, which should work.

To reply, lose the capitals and do the obvious.

Take a look at cpRepeater, an NMEA data integrator, repeater, and
