Novell NetWare supports MS-NET and, optionally, NetBIOS functions, which are described earlier in this chapter. Novell NetWare also supports the NetWare and IPX/SPX APIs, both based on Interrupt 21h.
Windows applications cannot make NetWare calls by using Interrupt 21h directly, because this method is not supported in all Windows operating modes. Instead, the Interrupt 21h instruction should be replaced by a far call to the NetWareRequest function. This function is exported by name from the NetWare DLL and should be imported to the module-definition (.DEF) file as NetWare.NetWareRequest.
Windows applications cannot make IPX/SPX calls at this time, although Novell plans to make this support available in a future release. For more information, contact Novell product support.
