Connectivity to CICS

There is a choice of network protocols for connecting to CICS®.

Note: In these descriptions, the terms "local mode" and "remote mode" refer to whether the connection between Client application and Gateway uses a network connection. See the related topics for more information on running in local mode or remote mode.

All protocols support ECI COMMAREA requests.
