Resident.
Clears CONTASK stack and returns all blocks to
free storage. Processes completed COBTASKS for virtual console
spooling, return or no return options, and
returns the CONTASK blocks to free storage. Starts and queues a console read request.
Synchronizes virtual machine console activity
with internal supervisor activity. This is used
during a virtual system reset and during the
logoff process.
Disconnects a virtual machine and sets a TeD
clock comparator request to log off the virtual machine after a fifteen-minute delay. Starts and queues a console write request.
Resident.
This is the second-level interruption handler for
remote 3270 stations. This module supports the 3270 remote display and printer stations. It
processes interruptions and CCis for the remote
stations, including message handling and screen
management.
Resident.
Supports the 3270 remote display and printer
stations. It processes interruptions and CCis for
the remote stations including message handling
and screen management.
Initializes and schedules CONTASKs. Enables and disables bisync lines and remote
stations.
Resident.
Exists as a CSECT and defines the machine's
configuration. A basic DMKRIO is shipped with VM/370. DMKRIO can be changed at system
generation or whenever new machines are added by
using the appropriate macros.
Residency not applicable. Invoked
via the NCPDUMP command in CMS. This is the interface between the VM/370 dUmp spool file and the OS-SSP dump format program for
printing and formatting dumps of the 3704 and 3705 communications controllers.
Resident.
Initializes and schedules the CONT1SK fields that
comprise the 3704 and 3705· Network Control
