When using the MSCOMM.VBX provided with Visual Basic version 2.0 or 3.0 to communicate with a 14.4 baud modem, the OnComm event may not fire. The revised version of the MSCOMM.VBX control available on CompuServe fixes this problem by introducing a new Notification property. Since the problem relates to using Windows 3.1 event driven communications, this new property allows you to use Windows 3.0 polling techniques instead.
