### Requirements for SNA

The IBM CS/UnixWare software (eNetwork Communications Server package) must be installed to configure a SYNC 2000 SDLC connection.

CS/UnixWare is a software product that enables SCO UnixWare 7 computers to communicate with remote computers (IBM mainframes, PCs, or other SCO UnixWare 7 computers) within an IBM SNA network. It provides SNA node type 2.0 and 2.1 support for communicating with host and peer computers. It also implements an APPN node, providing end node or network node function, depending on its configuration.
