NAME

  sys_attrs_scc, sys_attrs_scc_input - scc and scc_input subsystem attributes


DESCRIPTION

  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

  scc_cnt
      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)

  scc_major
      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.
