to give some precision, dio allow direct access to tty, ..
exmple:
$DEVICE="/dev/ttyS1";
$LOCK="/var/lock/lockdev/LCK..ttyS1";

-----
$fd = dio_open($DEVICE, O_RDWR |O_NOCTTY | O_NONBLOCK );
if (! $fd ) {
    LogErrors($myErrors,"Error opening $DEVICE");ABORT("error opening
$DEVICE ");}

$param = array( 'baud' => 9600, 'bits' => 8, 'stop'  =>1, 'parity' => 0);
if ( ! dio_tcsetattr($fd, $param) ) {
           dio_close($fd);
           ABORT("Error while dio_tcsetattr \n");
}

$rc = dio_write($fd, "\r");
sleep(1);
while ($rs != ":" ) {
    $rs = dio_read($fd, 1);

$rc = dio_write($fd, "E0\r");

$rs = "";
$x =0;
while ($rs != ":" ) {
    $rs = dio_read($fd, 1);
    $x++;
    if ( $x > 10000 ) { LogErrors($myErrors,"Timeout waiting
