Sign-on capable and sign-on incapable terminals

Sign-on capable terminals allow sign-on transactions, either CICS-supplied (CESN) or user-written, to be run, whereas sign-on incapable terminals do not allow these transactions to be run.

If a terminal resource is installed as sign-on capable, the application or user is responsible for starting a sign-on transaction; the user ID and password, once entered, are embedded in the 3270 data. If the terminal resource is installed as sign-on incapable, the user ID and password are authenticated for each transaction started for the terminal resource.
