Windows Standard Serial Communications Library for Visual Basic

The Marshallsoft serial communications component library for Visual Basic (WSC4VB) is a serial communication library based on the Windows serial comm API. WSC4VB uses the standard Windows API to communicate with any device connected to a serial port from within a VB or VB.NET application. The component library includes 28 functions + modem control, ASCII/XMODEM/YMODEM protocols, and a good selection of VB and VB.NET example programs. The library can be used with any version of Visual Basic (including VB.Net) or Visual Basic for Applications (VBA). Features include:
