The NDIS driver enables the iSPAN-Serial WAN adapter to 
emulate a LAN adapter. It supports the transportation of 
TCP/IP and IPX/SPX protocols over WAN serial lines. The 
NDIS driver enables the adapter to connect simultaneously to 
TCP/IP and IPX/SPX LANs over dedicated leased lines or 
through Frame Relay or X.25 networks. It is available for PPP, 
X.25, and Frame Relay data protocols.

This chapter explains how to install the NDIS software on 
Microsoft Windows NT 4.0 systems. Use this process to install 
the Base driver, Base driver utilities, NDIS driver, and NDIS 
driver utilities. This chapter also explains how to remove NDIS 
and Base driver software, if required.

After installation, you can create up to four NDIS driver 
configurations (referred to as logical adapters) on the server 
for LAN connections. This multi-driver capability on the 
server side enables remote users to connect to the server 
through different networks simultaneously over serial lines. 
NDIS driver connections provide remote access to services 
typically available to LAN-connected users, such as file- and 
print-sharing, database access, and messaging.

To install the NDIS software, follow these basic steps:

1. Verify that your system meets minimum requirements.

2. Install the Base driver and NDIS driver, with 

accompanying software.

3. Set up WAN properties.
