       sys_attrs_scc,  sys_attrs_scc_input  -  scc  and scc_input
       subsystem attributes

DESCRIPTION    [Toc]    [Back]

       This reference page lists and describes attributes for the
       serial driver (scc) and keyboard driver (scc_input) kernel
       subsystems used on the  DEC  3000  family  of  processors.
       Refer  to the sys_attrs(5) reference page for an introduction
 to the topic of kernel subsystem attributes.

   scc Subsystem
              Number of configured communication  ports.  On  DEC
              3000  family  systems, communication ports are configured
 for the keyboard and the mouse, in addition
              to  terminals.  The scc_cnt value is query only and
              cannot be changed by users.

              Default value: 4 (configured communication ports)

              The major number assigned  to  the  device  special
              files  /dev/tty00  and  /dev/tty01.  The  scc_major
              value is query only and cannot be changed by users.

              Default value: 24

   scc_input Subsystem
       The  DEC  3000  serial keyboard scc_input kernel subsystem
       has an internal-only debugging attribute that users should
       never modify.
