Specifying the sign-on capability of a terminal

Prior to Version 3.1.0 of Clients and Gateways, whether a terminal was sign-on capable or not depended upon the server implementation. Client terminals installed on distributed CICS® servers were sign-on capable; terminals installed on mainframe CICS and CICS Transaction Server for iSeries™ servers were sign-on incapable.

In Version 3.1.0, extended EPI function was introduced to allow the sign-on capability of a terminal to be specified by one of the following methods.

The sign-on capability of the installed terminal is returned in the terminal attributes. This will be set to SIGNON_UNKNOWN if the server does not return a sign-on capability parameter in the terminal install (CTIN) response.

To use any of the extended EPI functionality, ensure that you have applied the relevant server APAR; see CICS server PTF requirements.
