Vbio.dll 1.3

Vbio.dll (16bit & 32bit) is intended to read and write PC I/O ports in Windows 3.x/95/98 application. In old Quick Basic, there are two functions INP and OUTP which enable users to access I/O ports. But they are missing in Visual Basic. There are lots of people in newsgroup requesting similar feature, so I decide to release Vbio.dll as the replacement of INP and OUTP. This DLL is very useful especially when you develop a hareware device and want to interface it in your Windows application. 16-bit and 32-bitVisual Basic samples are included. You can also use it in other languages, such as FoxPro/Visual FoxPro, Delphi, and so
