CICS® 3270 terminal emulation enables a CICS Universal Client system to operate as a 3270 display for CICS applications, without needing a separate 3270 emulator product. Multiple CICS 3270 emulation sessions can run to one or more CICS servers.
You can use mapping files to customize the screen color attributes and keyboard settings of the client emulator, for example, to comply with company standard keyboard layouts.
CICS Client terminal definitions are autoinstalled on the CICS server and do not have to be predefined.
