TCP/IP Direct Connect software included with the PCI ESCON Adapter provides
TCP/IP Direct Connect provides an interface compliant with the Network Driver Interface Specification (NDIS). This allows Microsoft’s TCP/IP stack to communicate with the ESCON adapter in the same fashion it would use to communicate with any other network interface card (NIC). TCP/IP applications running on the server can communicate across the ESCON adapter with peer applications running on the IBM mainframe (Figure

Further, when Windows is properly configured for IP forwarding, any client in a TCP/IP network can gain immediate access to TCP/IP applications and/or services running on the mainframe (Figure
