Funny?!? Light actually is an electromagnetic radiation! Just in a range of frequencies in the hundreds of terahertz... And the principles on wich lasers and leds are built upon, sometimes are the same ones used to emit electromagnetic radiations at lower frequencies (read, tenth of gigahertz).
Solar cells are actually able to extract energy from light because, with these therahertz frequencies, ligth's electromagnetic radiation carries enough power to interact with semiconductor's atomic structure, and generate electron's flow...

dedNo, it's just a common AT string:

And, by the way, this is coming from Italy thru a V90 USRobotics Sportster Message Plus modem... 9 years and no line upgrade available here... Sigh...
