Logging Out

To gracefully log out of a session, a Logout Request message should be sent by the TPH. CFE will finish sending any queued data for that port and will then respond with a Logout Response message and close the connection. After receipt of a Logout Request message, CFE will ignore all other inbound (TPH to CFE) messages except for Client Heartbeat.
