In CICS TS for z/OS, Version 3.1, local TCAM terminals are not supported. The only TCAM terminals supported are remote terminals connected to a pre-CICS TS 3.1 terminal-owning region by the DCB (not ACB) interface of TCAM. Thus, the only way in which TCAM is supported is by transaction routing or function shipping from a remote, pre-CICS TS 3.1, terminal-owning region, to which the terminals are connected by TCAM/DCB.
CICS does not support the DCB interface of TCAM directly. To use a terminal through this interface, you need to do so through an older version of CICS, as explained in Terminal access method support. In general, you use the same terminal control commands and options for such a device as you would if it were attached through VTAM. However, the path between your CICS application program and the terminal is much more complex, and consequently there are many more programming possibilities.
For programming information about the CICS-TCAM interface, see the Customization Guide for your older version of CICS (the terminal-owning region to which your TCAM terminals are connected).
