Data area QTVNO32785 no longer supported for wide-screen suppression

New ENBWIDE parameter on the Change TELNET attributes (CHGTELNA) command must be used to configure wide-screen preferences.

Beginning with V5R1, customers who used 3278-5 wide-screen devices used for IBM® z systems and then wanted to Telnet to an IBM i system had an option to NOT use the wide-screen support and instead use a 24x80 display. This was documented and configured by creating a QTVNO32785 data area anywhere in the system library list.

Customers were instructed:

To get a 24x80 display, run the command CRTDTAARA DTAARA(libname/QTVNO32785) TYPE(*CHAR) VALUE(’1’).

This is no longer supported. The change is to use the Enable 3270 wide-screen (ENBWIDE) parameter added to the Change TELNET Attributes (CHGTELNA) command. Customers who previously used the QTVNO32785 data area must manually configure the Enable 3270 wide-screen (ENBWIDE) parameter. The system does not automatically migrate any pre-existing use of the QTVNO32785 data area and the default value of ENBWIDE(*YES) is used. The value for the ENBWIDE parameter must be set to *NO to disable wide-screen emulation.
