Com Ports and the MSComm. Little on the MSDN and on other VB sites is the COM port, and how to use it in Visual Basic. A serial port for. MSCOMM – Visual Basic [Serial Port Functions] - Free download as PDF File (.pdf), Text File (.txt) or read online for free.

Rhythm X Audition Packet Pdf Writer. Excel can communicate in and out the serial port both with API calls and with the MSCOMM.OCX control. Both techniques require some fairly serious VBA code as well as a deep understanding of either the Windows communications API or the intricacies of the MSCOMM control. I can tell you from experience that the first option is absurdly difficult and the second option is not altogether reliable. I have heard that the latest release of the MSCOMM.OCX control is more stable than the original however I have never had good results with it. You may want to look at some of the other commercial communications OCXs out there.

If you are interested, the company that I work for sells a serial communications program called the Software Wedge that you may find to be a good tool for adding serial communications capabilities to your application. The Software Wedge is an executable program that can pass serial data back and forth to other programs using either DDE (Dynamic Data Exchange) or by converting incoming serial data to keystrokes (i. Linhof Technika Serial Numbers. e.

It stuffs the keyboard buffer with the incoming serial data). The program is extremely easy to use and is designed to have you up and running sending and receiving serial data directly from within your application in just a few minutes.

I would recommend getting a good book on it like the Visual Basic Programmers Guide to Serial Communications by Richard Grier.
