Some Notes on HTTP Post
HTTP post requires a Web address to be entered into the server:port field in the setup screen
which points to a script able to accept several variables. The variables are hardcoded from the
program and consists of all the values used in a position report. Low is the name of these values,
and an example PHP script to accept and log the data.
