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.
