Chapter 11 - Ethernet, Token Ring, and Fiber Distributed Data Interface

Ethernet, Token Ring, and FDDI Reference

This section describes the Ethernet data structures and functions. You use these data structures and functions to communicate directly with the Ethernet, token ring, and FDDI drivers. The functions were originally designed to read data from and write it
to the Ethernet driver. However, by specifying the appropriate driver reference number, you can also use many of these functions for the token ring and FDDI drivers.

Some of the Ethernet functions do not apply to token ring and FDDI. Each of the functions includes a section called Token Ring and FDDI Considerations that identifies whether the function is valid for these drivers.

The "Data Structures" section shows the Pascal data structures for the write-data structure and the ENET parameter block of type EParamBlock.

The "Routines" section describes how to

• attach and detach a protocol handler to receive data from an Ethernet driver
• write data to the Ethernet, token ring, or FDDI driver
• read data from the Ethernet driver and cancel a function request to read data from the driver when you use the default Ethernet protocol handler
• obtain information about the Ethernet driver and switch its mode to handle
  larger packets
• add and remove a multicast address for an application that uses the Ethernet or FDDI driver and a functional address for an application that uses the token ring driver
