Preparing QWS3270 Secure for HLLAPI
...
By default, HLLAPI support is disabled in each session. To activate it for a specific session, select Options/Session/Host Settings menu item. The dialog includes a drop-down box that allows the selection of an HLLAPI Session ID (A-Z). Choose a letter that is unused at the time by any other HLLAPI applications that are connected to the same host.
If you are using a commercially distributed application that interfaces with a 3270 emulator via HLLAPI, configure the application as you would for use with the IBM Personal Communications/3270 package.
