If you specify TN3270E_CONNECT Y, which implies TN3270E Y (see TN3270E), then TN3270E support is taken a step further.
This parameter is applicable to the SYSTEM control statement (see SYSTEM statement).
TN3270E_CONNECT [Yes|No|ON|OFF]
When TN3270E_CONNECT Y is in effect, the device name supplied by the client will be used to nominate a virtual terminal (VTAM ACB) which may be used when subsequently establishing forward sessions. This device name may relate to either a specific ACB or a range of ACBs.
For more information on TN3270E support and user-level session ACB support, see the Installation and Customization manual.
