Strange I discovered that if I run this from the command line as root it
works. If I start Firefox even as root and run the program from the
browser I get the error ..

Warning: Specified serial port is not valid
in /usr/share/php/php_serial.class.php on line 111

I tried changing permissions on the file to give permissions to anyone
to execute and you still have to be root in the command line to make it
run properly and it still won't run via the browser. Any idea whats
going on here?
