I think I've not explained myself properly. The modem wants a carriage return. That is a \r. It doesn't matter what OS you are on. If you don't send the right string to the modem, then the modem won't process it properly. If your OS maps \r to PHP_EOL, then, obviously PHP_EOL will be just fine. But I would recommend ... <?php define('CR', chr(13)); ?> -- Richard Quadling Twitter : EE : Zend : PHPDoc : Fantasy Shopper @RQuadling : e-e.com/M_248814.html : bit.ly/9O8vFY : bit.ly/lFnVea : fan.sh/6/370
