Com Ports and the MSComm Control - Introduction

James Crowley

Introduction

One subject that seems to be discussed very little on the MSDN and on other VB sites is the COM port, and how to use it in Visual Basic. Therefore, in this tutorial, we will discuss detecting the available COM ports, and using the Microsoft COMM control to communicate with COM ports.

James first started writing tutorials on Visual Basic in 1999 whilst starting this website (then known as VB Web). Since then, the site has grown rapidly, and James has written numerous tutorials, articles and reviews on VB, PHP, ASP and C#. In October 2003, James formed the company Developer Fusion Ltd, which owns this website, and also offers various development services. In his spare time, he's a 3rd year undergraduate studying Computer Science in the UK. He's also a Visual Basic MVP.
