You are right, the underlying logic of Logon request, Logon response, TestRequest, Heartbeat, is same. Some tags / values are different between FIX.4.0 / 4.1 / 4.2 and FIXT.1.1 introduces new structure because of transport indenpendence. You will discover many interesting things writing both the initiator and acceptor. A lot of code is common between these.
