+es of Code.

You should use the same device name that works in your other scripts.

#$port->write_settings || undef $port;

Why did you commment this out? Try uncommenting this.

Although I've used Device::SerialPort successfully in the past, I now strongly recommend IO::Termios on *NIX systems instead - see my post Lower-Level Serial Port Access on *NIX.
