This is the homepage of Ocean Controls' Kit108 serial device (Serial Digital Input and Output Controller) PHP library.
The library is known to work under Linux, and while this has never never been tested, it is pretty much expected NOT to work under Windows – while relay commands MIGHT work under Windows, reading the inputs will almost certainly not.
The library is available under the GNU GPL license. The library is here (tar.gz file). The documentation is here. You can find a tutorial here. You can contact the author via e-mail as provided in the documentation.
