Why World Wide Web Browsers need permission for Serial Ports

Giant Robots.

Before recorded time, nineteen seventy to be exact, computers communicated with giant robots through serial ports and radio transmissions. It is done as a precaution to not accidentally reactivate one of these behemoths.

The historical recordings show the damage robots, both giant and regular size, can cause. From Maria to Mechagodzilla, the early robots were no longer to be trusted.

Johnny Sokko’s Flying Robot was a pivotal moment with the passing of the international robot law. In one historical recording, Giant Robo did not respond to Johnny Sokko’s command. While Giant Robo did act in a good and in a defensive manner, he did act on his own without obeying a human.

“Even if it is a child, does it think it knows better than us?”

No one disagreed at the international court and the international robot law was passed.

Some said the robots were a victim of prejudice. The rest said something about selling out the human race.

Radio communication to robots both large and small were outlawed. Communication with them was only allowed through wires so someone would be directly responsible for the robot’s actions.

Exceptions were allowed. Notable robots included ‘Robby the Robot’ and ‘Robot Model B-9’. They had performed without flaw and were beloved by the public. Sometimes you will find them touring at a historical recording convention.

That’s why you need to give permission to use a serial port.
