wtf is ser?

The repository named "ser" is a tool that helps programs written in C++ communicate with devices over a serial port. Serial ports are a common way for computers to talk to external hardware like microcontrollers, sensors, or older electronics. This library gives a developer a ready-made way to send and receive data through those connections. Without a library like this, setting up a serial connection in C++ can be tedious and platform-specific, meaning you often have to write different code depending on whether you are using Windows, Linux, or macOS. This project aims to simplify that process by providing a straightforward interface so the developer can focus on the actual data exchange rather than the underlying plumbing. Someone would use this if they are building a desktop application or backend system that needs to talk to physical hardware. For example, a developer building a control panel for a custom 3D printer, a program that reads temperature data from an Arduino sensor, or software that interfaces with industrial equipment would need serial port communication. The README doesn't go into detail about specific features or usage examples, so it is hard to say exactly how many convenience functions are included or how it handles edge cases like connection drops. It is a small, focused utility written in C++, which suggests it is meant to be lightweight and easy to integrate into an existing project that needs basic hardware connectivity.
