Mini - Mini Magnetic Swipe Card Reader USB or Port Powered Bi-directional

John was fascinated. He had stumbled upon a mysterious conversation happening on his own computer, and he had no idea what it meant. He decided to respond to the client, typing Hello and hitting enter.

The server responded immediately: Hello John. We've been waiting for you .

Over the next few hours, John conversed with the server, discussing his project and receiving valuable advice. The server provided code snippets, debugging tips, and even suggestions for new features.

John was puzzled. He had no idea what process could be using that port, or what it was waiting for. He decided to try and connect to it using a tool like telnet . He typed telnet localhost 11501 and hit enter.

The next morning, John woke up feeling inspired. He opened his terminal window and typed localhost:11501 free . The message still appeared, but this time, he knew what it meant. He knew that he had access to a powerful tool, one that would help him become a better developer.

And so, the legend of localhost:11501 free lived on, a reminder to developers everywhere that sometimes, the most unexpected tools can be the most valuable of all.

John's eyes widened. How did the server know his name? He typed Who are you? and hit enter.
