Processes the NETWORK POLLDLAY command.
Processes the NETWORK TRACE co.mand. Processes the NETWORK VARY NCP command to switch
an EP communication line to NCP mode. Pageable. Decodes NETWORK Enable binary
stations. NETWORK command Pageable. command and enables bisync lines.
synchronous lines and remote decoder. Dumps the 3705 network control program. Loads the 3705 network control program. These
routines may be called by a console command from DMKNET or or internally by DMKCPI (for LOID) or DMKRNH (for DUMP). Pageable. Dump the 3705 Network Control Program. Resident. Provides the necessary support for the VM/370 system console. Certain routines within the
control program cannot call DMKQCN to issue
writes to the system console. This module determines the system's primary console and
builds a channel program to handle the requested
call.
Resident.
Constructs IOBLOKs and schedules the tasks that move virtual storage pages between auxiliary
storage and main storage. It also calculates the
total system paging load at user-specified
intervals. Pageable. Sets a return code of zero in R2.
Resets the interruption.
Resets program event recording. Pageable. Release all the pages of a user's virtual storage from the real storage and from auxiliary storage
on the paging device.
Releases a specified part of virtual storage.
Calls DMKPTRPU to ensure that the user is not in
page wait and then releases the address range
contained in Rl through R2. It also unlocks any
pages that might have been locked.
