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
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.

sys_attrs_isa - isa subsystem attributes
DESCRIPTION
This reference page lists and describes attributes for the ISA Bus (isa) kernel subsystem. Refer to the sys_attrs(5) reference page for an
introduction to the topic of kernel subsystem attributes.
For this subsytem, users should modify only the following attribute and do so only for the purpose described. Any other visible attributes
cannot or should not be modified.
Enables (1) or disables (0) console messages that are used by driver developers to collect information about a configuration prob-
lem. A developer can set this attribute by using the sysconfig or sysconfigdb utility. See sysconfig(8), sysconfigdb(8), and cfg-
mgr(8) for more information on options for modifying attributes and reconfiguring a kernel subsystem.
Default value: 0
