Remote Spooling Communications Subsystem: Overview
TheVM/370 Remote Spooling Communications Subsystem (RSCS) is the component that provides for the transmission of files across a
teleprocessing network controlledby the VM/370 computer. Using RSCS, virtual machine users can transmit files to remote stations. (Remote
stations areI/O configurations attached to the computer by communications lines.) Also, users at remote stations can transmit
files toVM/370 virtual machines and to other remote stations using RSCS. RSCS resides in a virtual machine dedicated to remote spooling. Using the RSCS command language, the RSCS operator manages the
telecommunications facilities for the installation.
Operators at remote stations can manage their own configurations
using a subset of the command language. Commands issued from remote
stations can be entered either at a terminal or from a card reader.You can find detailed
publication descriptions of RSCS functions in the (RS£.2) The RSCS Virtual Machine and the VM/370 Control Program (CP)
Like the otherVM/370 virtual machines, the RSCS virtual machine runs under the control of CPe In extending the VM/370 spooling system capability to include spooling to remote stations, RSCS interacts with
theCP spooling system. Therefore, some of the information in this
publication requires a knowledge of that area ofCP. The RSCS virtual machine consists of the virtual machine operatcr
console, anRSCS system disk, and virtual telecommunications lines.
During system generation, a virtual card reader is defined for theRSCS virtual machine, but this reader does not exist in the CP directory
