This file contains lines of various forms and is used by config(1M) to obtain device information that enables it to generate the configuration file.

Software drivers are defined as follows:

Field 1 Device name, used in the user-specified dfile.  (8 characters maximum)

Field 2 Handler name, used by the kernel to prefix routines such as cs80_read, lp_write, and others. (8 characters maximum)

Field 3 Element characteristics: Five bits make up the mask

Bit 1 - card
Bit 2 - specified only once
Bit 3 - required driver
Bit 4 - block device
Bit 5 - character device (LSB)

Field 4 Functions for the device: Twelve bits make up the mask

Bit  1 − option1 handler (Series 700 only)
Bit  2 − dump handler
Bit  3 − size handler
Bit  4 − link routine
Bit  5 − open handler
Bit  6 − close handler
Bit  7 − read handler
Bit  8 − write handler
Bit  9 − ioctl handler
Bit 10 − select handler
Bit 11 − seltru handler
Bit 12 − C_ALLCLOSES flag (LSB)

Field 5 Major device number if a block-type device; otherwise −1. 

Field 6 Major device number if a character-type device; otherwise −1. 

Aliases for names are defined as follows:

Field 1 Alias name => product number (8 characters maximum)

Field 2 Device name (8 characters maximum)

Parameters are defined as follows:

Field 1 Parameter name, as used in the user-specified dfile (20 characters maximum). 

Field 2 Parameter name, as used in the #define statement in conf.c (20 characters maximum). 

Field 3 Default value for the parameter (60 characters maximum).
