Open Data-Link Interface (ODI) is another similar API that was used primarily by Novell NetWare and Apple Macintosh environments. The Network Driver Interface Specification (NDIS) is a similar API used primarily with Microsoft Windows. A packet driver makes the hardware and network accessible in an easy manner.

Your TCP/IP code really does not care because the packet driver provides a consistent way to send packets and receive packets from the chosen network hardware. That hardware might be a network adapter, an Ethernet chipset connected through the parallel port, or even just a plain serial port. Inside the packet driver is code to talk to a specific piece of hardware. The complexity of the hardware is hidden by the packet driver. It talks to the packet driver for that hardware, and as far as the networking software is concerned all packet drivers all look and behave the same way. The packet driver for an adapter is effectively the device driver for the adapter.Īnother way to look at it is that your networking software never really talks directly to the networking hardware. Decoupling the network hardware programming from the applications made the applications smaller and less complex while allowing them to handle new adapters with no changes.

Application software would use the API to send and receive packets. A device manufacturer needed to provide a packet driver, which was a small TSR that provided the API in the form of software interrupts.

created the PC/TCP Packet Driver specification which defined an API for sending and receiving packets over networking devices. Packet Drivers Collection for MS-DOS, IBM PC-DOS, DR-DOS, FreeDOS, etc.
