CommAPI translates the communications functions of Windows API to AutoIt functions.

Overview

Features

  • No need to install DLL's
  • Using Windows API calls (kernel32.dll)
  • Possibility of serial communication (serial port, COM port, RS-232)
  • Possibility of parallel communication (parallel port, LPT port)
  • No use of global variables
  • Uniform namespace _CommAPI_XXX
  • Modular organization into files
  • A lot of additional utility and helper functions

Scripts

Examples

CommAPI Examples shows you some examples. Maybe you could find more examples in forum.
