Description
Section 4 describes the special files, related driver functions, and networking support available in the system. In this part of the man-
ual, the Syntax heading of each configurable device gives a sample specification for use in constructing a system description for the pro-
gram. The Diagnostics heading lists messages that may appear on the console and in the system error log file due to errors in device oper-
ation.
This section contains descriptions of both configurable devices, 4 entries, and network-related device information, 4n, 4p, and 4f entries.
The networking support is introduced in Software support for these devices comes in two forms. A hardware device may be supported with a
character or block ``device driver'', or it may be used within the networking subsystem and have a ``network interface driver''.
There are some devices that have fixed input/output space CSR addresses and interrupt vector addresses. There are no address switches or
jumpers that need to be set up by the customer or Field Service.
