Remote Spooling Communications Subsystem Version 3 Release 2.0

RSCS Version 3 Release 2.0 offers two major enhancements that greatly expand your print/connect operations.

• 31-bit addressing enables RSCS to use storage above the 16 Megabyte line which permits expansion of networks to more links.
• A socket interface and three TCP/IP line drivers allow RSCS to utilize a TCP/IP network.

31-bit Addressing

RSCS Version 3 Release 2.0 will provide 31-bit addressing and allow RSCS to now use storage above the 16 Megabyte line. The current RSCS Version 3.1.1 has a storage constraint that requires customers to use multiple RSCS servers to define their network. This support will extend RSCS to use 31-bit addressing for all possible data areas and for all I/O areas and allow customers to define more links in their RSCS machine.

Transmission Control Protocol/Internet Protocol (TCP/IP) socket interface

Providing a TCP/IP socket interface and three line drivers will allow RSCS to utilize a TCP/IP network. The three line drivers are:

• A line driver providing the ability to allow Network Job Entry (NJE) traffic to flow over a TCP/IP network from RSCS to another NJE node.
• A line driver to transmit RSCS print output to ASCII printers attached to terminal servers within a TCP/IP network. This can be used to support workstation printers utilizing TCP/IP as the transport medium.
• A LPR driver to send datastreams to a TCP/IP line printer daemon for distribution or printing. This provides a gateway from any network to an IP print daemon.
• A socket interface is provided that enables customers to code their own RSCS TCP/IP drivers.
