BARR/SYNC for Microsoft Networks Overview

Few downstream devices offer the ability to simultaneously send data to and receive data from a single device on an SDLC link. Although this capability is supported by virtually all front-end processors (FEPs), most SNA gateways and controllers allow duplex operation only on distinct sending and receiving devices. Independent testing has shown that the Barr adapter used by BARR/SYNC for Microsoft Networks can actually double bidirectional traffic at a given SDLC link speed. This is achieved by supporting the DATMODE=FULL parameter. Even when most of the SNA traffic goes in one direction, performance can be significantly improved because acknowledgments can be transmitted as the software receives data.

BARR/SYNC for Microsoft Networks includes the following features and benefits.
