NAME
intro − introduction to special files and hardware support
DESCRIPTION
Section four describes the special files, related driver functions, and networking support available in the system. In this part of the manual, the SYNTAX 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 which may appear on the console and in the system error log file /usr/adm/syserr/syserr.<hostname> due to errors in device operation.
This section four area contains descriptions of both configurable devices, “4” entries, and network related “device” information, “4n”, “4p”, and “4f” entries; The networking support is introduced in intro(4n). 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.
