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.
