APPENDIX A: 3274 SNA Communication Operations

NOTE

Some applications may not send a welcome message. The operator must send the first message to start the transactions.

8.After the operator has finished working, he should signoff the application. The system will then UNBIND the CRT so that the CRT and applications are no longer communicating with each other. This leaves the CRT available for an operator to logon to another application. The 3274 controller will usually clear the CRT when this happens. SSCP will then send an enter request logon message which puts the CRT back to step 4 so as to start things over again.
