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));
?>
