SUMMARY

If you use TCP/IP socket applications from within Microsoft Windows, VSOCKETS.386 must be present to ensure data integrity. To prevent problems with Windows context switching, this driver ensures that data sent is in global memory rather than local memory. For applications using BAPI from within Windows, the VBAPI.386 driver should also be installed in addition to the real-mode sockets and BAPI drivers.

Failure to install these drivers may result in data corruption if you use socket applications from an MS-DOS box within Microsoft Windows.

  1. Copy VSOCKETS.386 and VBAPI.386 to the Windows directory.
