I thought since I can write to it in the same way as I would write to a file that I could read it in the same way as I would read a file. But when I try to read it (using the code below) I just end up in an infinite loop. Lua Serial Port Introduction. This project implements a Serial Port module for Lua. It currently only supports Linux, and requires LuaJIT FFI.

A Lua library for the Arduino written in C This is using the POSIX library which should work on oUNIX environments. Using this library you'll be able to send and receive data from the Arduino. See the arduinotest.lua and arduinotest.ino for an example of sending data to the arduino and then receiving the data back.
