sys_attrs_scc(5)sys_attrs_scc(5)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
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 inter‐
nal-only debugging attribute that users should never modify.
