Hello List, I am searching information about serial communication with PHP on Windows machines. I want to communicate with a colorimeter via a COM-Port, using a PHP-GTK application. Can anybody point me into the right direction (a webpage, a PHP class/function, a PHP-GTK list) where I can find infos about this? I searched the web for some hours now but didn't find anything worthy. Any help is greatly appreciated! thanks in advance! best regards Ulrik Witschass
