The logon message is utilized to authenticate a user attempting to establish a connection to a remote system. The logon message must be the first message sent by the connecting application.
The HeartBtInt (108) field is used to declare the timeout interval for generating heartbeats.
The sequence number field is not incremented for a Logon message, thus the sequence number contained in the message should be used for resynchronization purposes on restarts. It is always necessary to complete the Test Request - Heartbeat initialization sequence to guarantee proper resynchronization.
Logon messages are NEVER retransmitted as the result of a resend request.
