predefined

Purpose

     Provides information for predefined devices.

Description

     The predefined  file contains information  about hardware
     adapters and devices that is used by the devices command.
     Some of these devices may  not be present in a particular
     configuration,  but  all of  them  are  supported by  the
     system.  The predefined  file contains information needed
     when adding one of these devices  so that you do not have
     to  supply the  information yourself.   The size  of this
     file increases  with new  entries as  additional licensed
     programs are installed in the system.

     The devices command uses the  information in this file to
     set  up stanzas  in  the system  and  qconfig files  when
     devices are  added to the system.   Note that information
     in this  file has  no effect  on the  system until  it is
     moved to a stanza in the system or qconfig file.

     The predefined  file is similar in  structure and content
     to the  system file, and  its stanzas can contain  any of
     the keywords  that are allowed  in the system  file.  See
     "system"  for  a description  of  the  keywords that  can
     appear in stanzas of these files.

     The use of extended characters  in the predefined file is
     not supported.

     The predefined file contains several special stanzas:

     defqueue    Used  by the  devices command  to create  the
                 queue  stanza  in  the qconfig  file  when  a
                 printer or plotter is added.

     defdevice   Used  by the  devices command  to create  the
                 device  stanza in  the  qconfig  file when  a
                 printer or plotter is added.

     default     Contains keywords  and their values  that are
                 common to all device stanzas.

     adpts       Contains  a list  of adapters  with the  code
                 number  and  description   that  the  devices
                 command uses to identify each one.

     addrs       Contains a list of  adapters and their corre-
                 sponding adapter type and address.
