intro(7) — Special Files

NAME
intro − introduction to special files
DESCRIPTION
The Section 7 DEC OSF/1 reference pages are made up of an OSF-supplied component and a Digital-supplied component. The title line of an OSF-supplied reference page carries an "OSF" label while the Digital-supplied reference pages are labeled "Digital".
If OSF-supplied code operates differently on Digital platforms or has Digital extensions, an Environment Notes section is added to the OSF-supplied reference page. All reference pages that have an Environment Notes section have an "Environment_Note_Added" label added to the title line.
When needed, technical corrections have been made to the OSF-supplied reference pages.
The suffixes used on some Digital-supplied reference pages are used only to allow reference pages with the same base name to exist on DEC OSF/1 systems. When used, suffixes are made up of one to four letters. See the man(1) reference page for more information on suffixes.
Section 7 describes the special files, related driver functions, and networking support available in the system. In this part of the manual, the SYNOPSIS heading of each configurable device gives a sample specification for use in constructing a system description for the config(8) program. The DIAGNOSTICS heading lists messages that may appear on the console and in the system error log file /usr/adm/syserr/syserr.<hostname> due to errors in device operation.
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.
