# librs232

## Multiplatform library for serial communications over RS-232 (serial port)

[![Build Status](https://travis-ci.org/srdgame/librs232.svg?branch=master)](https://travis-ci.org/srdgame/librs232)
[![Build status](https://ci.appveyor.com/api/projects/status/github/srdgame/librs232?branch=master&svg=true)](https://ci.appveyor.com/project/srdgame/librs232)

## Changes from the original version
* Windows. Use overlapped IO model.
* Windows. Support detect break/parity error.
* Windows. Implement `rs232_in_queue_clear`.
* Windows. Fix using static variables to support multithreading.
* Windows. `rs232_read` wait at least one byte (like in POSIX version).
* Basic tests on Travis/Appveyor.
* Lua. Export `rs232_in_queue_clear` / `rs232_in_queue` functions.
* Lua. Add more Lua way module.

## Lua binding

```Lua
local rs232 = require "rs232"

local p, e = rs232.port('COM1',{
  baud         = '_9600';
  data_bits    = '_8';
  parity       = 'NONE';
  stop_bits    = '_1';
  flow_control = 'OFF';
  rts          = 'ON';
})

p:open()
print(p:write('AT\r\n'))
print(p:read(64, 5000))
p:close()
```
