The cicsterm command controls 3270 terminal emulation. You can start emulator sessions, specify terminal emulator characteristics, and the names of the keyboard mapping and color mapping files.
You can have multiple terminal emulation sessions running simultaneously.
The cicsterm command detects whether the hardware on which the Client daemon is running is enabled for double-byte character set (DBCS) display. If it is, the emulator can display DBCS characters. Some uses of servers and protocols require a Model terminal definition for the emulator that explicitly specifies that the Client daemon wants to display DBCS.
For cicsterm emulators, the maximum screen size is 27 rows by 132 columns. This is because the Client daemon supports the ASCII-7 subset of the 3270 data stream architecture, which supports only 12 bit addressing. For more information, see CICS Transaction Gateway: Programming Guide.
The CICS® Transaction Server interprets cicsterm as a remote terminal. The execution diagnostic facilities CEDF and CEDX have some restrictions on remote terminals. Refer to your CICS Transaction Server documentation for details.
