Hi

If your scale uses the same settings as your OS (speed, etc) it should
be enough to fopen /dev/ttyS0 and use it like a file. Note: You can not
read and write with one socket - in this case you have to use two.

Example:

$string = "foobar\n";
$pointer = fopen("/dev/ttyS0","w");
fwrite ($pointer, $string);
fclose($pointer);
