BARR/SYNC for Microsoft Networks provides high-speed, full-duplex communications for Microsoft Host Integration Server 2000. The package includes the Barr SYNC PCI adapter, software drivers to work with the Host Integration Server 2000, diagnostics, and online help.

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, 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 bi-directional 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.
