Thanks for the many great replies, since at the moment the project is based on PHP4, I will try if the filesystem functions provide what I need. Opening the port and sending doesn't seem to be a problem, I'll try it out tonight. If for some reason it doesnt provide the functionality I need, I will take a closer look at migrating to PHP 5 (which shouldn't be a problem) and using the DIO functions. Thanx to everybody for the help they provided! best regards Ulrik -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
