Well if "other" has "rw" then it doesn't really matter who owns the file.

What does the php error log say?
Are any of the safe mode stuff enabled?
Are you running SELinux?

Anyway the following works for me:

error_reporting(E_ALL);
//error_reporting(0);
ini_set('display_errors', TRUE);

if (!$fp = fopen("/dev/ttyS0", 'w+b')) {
echo "\nError! Could not open COMport - Got a terminal open?\n";
exit;
} else {
$i = 0;
while ((false !== ($char = fgetc($fp))) AND $i < 10) {
$i++;
echo "$i::[$char]<br>";
}
echo $i;
}
