TCPDirect Sell Side Sample

This sample listens an incoming connection on the pre-defined interface and port (acts as a FIX Acceptor). When the session is established, and the SingleOrder - New is received, the ExecutionReport FIX message is sent to the counterparty. This is done using Solarflare TCPDirect© technology.
