Serial port software - RS-232 serial port communications in Visual Basic, C#, C++ and more.

Performing RS-232 communications in a Windows environment is a daunting task.

The Win32 Serial Communications API is notoriously complex, inconsistent, and difficult to use for even advanced C++ programmers. Message boards and newsgroups are littered with desperate requests from developers who are struggling to debug their serial communications code. Managers watch deadlines come and go as endless streams of bugs are uncovered. How can you keep this from happening to you?

PortController by Scientific Component - powerful serial port software. Build on the work of others! Scientific Component has spent years discovering the hidden pitfalls of RS-232 communication in Windows that the MSDN documentation glosses over. We've developed PortController.NET and PortController ActiveX to make performing multithreaded serial communications quick, intuitive, and above all, straightforward.

PortController.NET and PortController ActiveX are powerful, easy to use components that allow developers to perform serial communication tasks through a simple, intuitive API. PortController has been thoroughly tested and comes with extensive documentation and 12 sample projects. Using PortController in your applications can save you hundreds of man-hours that would otherwise be spent in development, documentation, and testing. Learn more about our serial port software - PortController.NET or PortController ActiveX.

Furthermore, because transparency is the key to long-term maintainability, PortController.NET and PortController ActiveX source code are available for purchase. You may use the source code to build custom versions of PortController for your application, or simply keep it for the peace of mind that comes with knowing you are in full control.
