Many years ago we wrote the original MSComm control in Microsoft Visual Basic. We then went on to develop Crescent PDQComm and Sax Comm Objects. Today CommStudio ActiveX is compatible with all previous generations, requiring no or minimal code changes to upgrade.
Replacing your existing control with CommStudio will speed up the development process, increase the quality of your application, and reduce technical support. That means less work for you and more satisfaction for your users.
