When I send a command directly from the terminal using the command : echo 1 > /dev/ttyUSB0 it works and '1' is transmitted to the serial port . But using php I get the above warnings . I dont understand where the problem is . Is it a permissions issue ? If not what could be the problem ? -- View this message in context: http://fedora.12.n6.nabble.com/php-serial-communication-in-linux-tp4938590p4939998.html Sent from the Fedora List mailing list archive at Nabble.com. -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
