Serial Port Over WiFi

Data communication between electronic devices is inevitable in many electronic projects and brings a lot of advantages to your project i.e. connecting your microcontroller to PC and monitor data on a large colorful display instead of small monochrome LCD. When talking about connecting a device to PC, the most obvious way of communicating is USB port. But transmitting data over USB requires lots of programming. Another easy way is Serial Port (aka COM) and RS232 protocol that only needs a tiny electronic circuit to convert voltage levels and a little programming. But long wires from devices to PC are annoying me. Is it possible to have the serial port on the air like wireless mice and keyboards? Of course, it can be done using lovely WiFi module ESP8266, and by using WiFi you have not to make a dongle yourself and also you can have a serial port over the internet. Wow, I just wanted a wireless serial port, now I also have a serial port over the web. That is very exciting.
