## What it is
A Go library for reading and writing to serial ports as a stream of bytes with a consistent cross-platform API. It supports configurable baud rates, blocking and non-blocking reads, and concurrent read/write from multiple goroutines.

## Use cases
- read and write to a serial port in Go
- communicate with an Arduino over USB serial
- talk to a device over a COM port on Windows
- cross-compile serial port code for Windows without cgo
- read data from a bluetooth serial port
- interface with embedded hardware via RS-232

## When to choose
- you need simple serial port I/O in Go with minimal configuration
- you need the same serial API across Linux, macOS, and Windows
- you want to cross-compile for Windows from another platform

## When to avoid
- you need configurable data bits, stop bits, parity, or flow control
- you need advanced serial features like line status signals or RS-485 support
- you need a library under active development with frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: file-system, developer-tools
- domain: developer-tools, hardware, embedded-systems
- platform: windows, go, cross-platform
- tags: serial-port, rs232, go-library, hardware-communication, usb-serial, linux, macos
