CommAPI

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

CommAPIConstants.au3
CommAPI.au3
CommAPIHelper.au3
CommUtilities.au3
CommInterface.au3
CommObsolete.au3 (only needed for backward compatibility)

Examples

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