Serial Communications in Win32

This article assumes a familiarity with the fundamentals of multiple threading and synchronization in Win32. In addition, a basic understanding of the Win32 heap functions is useful to fully comprehend the memory management methods used by the Multithreaded TTY (MTTTY) sample included with this article. (35 printed pages) Download the MTTTY sample (4918.exe) for this technical article.

Introduction Opening a Port The CreateFile function opens a communications port. Reading and Writing. Serial Port Communication in Excel (VBA) Introduction to Serial Port Communication in VBA The purpose of this article is to demonstrate how you can perform serial port communication in the VBA (Visual Basic Applications - script editor included in any typical Microsoft Excel distribution) but without using the MSComm control or any other third party add-on or ActiveX.

Serial Port Communication in Excel (VBA)

The great advantage of this method, which uses API functions to call the serial port directly, is that you do not really need to install anything on your PC, apart from the Excel itself (which, let’s admit it, already exists on most PCs). Other methods always require the installation of an ActiveX, or at least the registration of an “.ocx” file, like for instance the MSComm control.

Even the method of programming in C#, which I have suggested in a different article (Serial Port Communication in C#) needs the installation of the .NET Framework and of the C# compiler itself.
