Terminal Control Table Requirements

The Terminal Control Table (TCT) The TCT macro DFHTCT TYPE=TERMINAL specifies the CICS environment for IBM 3270 keyboard/displays and printers. This environment can include telecommunications devices, sequential processing devices, graphic devices, and intersystem and interregion links. The macro DFHTCT TYPE=SYSTEM defines the environment for remote systems served by an LU type 6.2.

This section describes the DFHTCT TYPE=TERMINAL and DFHTCT TYPE=SYSTEM operands allowed for HP's SNA products. HP requires that you define certain parameters or values as defined in this section. Other operands described are allowed with restrictions where indicated.

Parameter descriptions are in tables organized by LU type. These tables provide the experienced system programmer with most of the information needed to configure CICS. For more information, refer to the "CICS Macro and Operand Descriptions" section that follows, or the CICS/VS Resource Definition Guide for the remote system.

	WARNING! The HP SNA products are emulations of the IBM products. Thus, some parameters will need particular values based on the requirements of the HP products. Code these as specified or results are unpredictable. Any operands not listed are not allowed in the HP SNA services definitions and, therefore, are not supported. Any time spent solving problems related to incorrect configuration of the host is billable to the customer on a time and materials basis.

DFHTCT TYPE=TERMINAL Requirements

Tables 3-1 through 3-3 contain parameters for the DFHTCT TYPE=TERMINAL macro. This macro defines an IBM 3270 LU to CICS. One macro must be coded for each LU.
