    Hi all,

    I need to run python script that read/write to serial port
    (/dev/ttyS0). As root, i can run the script without problem but when i
    tried to involke it via browser ( apache2. PHP 4.3) i got error. The
    error is
       /dev/ttyS0 - Permission denied.

    i tried chmod go+wr /dev/ttyS0...but it not working. Please help me.

    BTW - im using Core 3 on i386, pySerial python module and apache2.
