Associating Terminals with Devices

Overview

Once you associate an autotask with selected logical terminals, you need to ensure that these terminals correspond to particular devices. You do this by associating logical terminal/physical terminal pairs with the appropriate devices.

UCF, VTAM, and TCAM

For UCF, VTAM, and TCAM, you can choose whether to associate a logical/physical terminal pair with a particular device. If you do not explicitly associate a terminal pair with a device, the system takes the first available pair when a user signs on.

Other Access Methods

For all other access methods, you must associate terminal pairs with devices. In this case, users are always assigned a specific logical and physical terminal when they sign on to a particular device.

How to Associate Terminals with Devices

To associate UCF, VTAM, and TCAM terminals with particular devices, you use the NAME IS parameter of the system generation PTERM statement.

Suppose, for example, that the system definition includes logical terminal LT12012 and physical terminal PT12012. To associate this terminal pair with device FT068109, submit this information to the system generation compiler:

MODIFY PTERM PT12012
    ACQUIRE
    NAME IS FT068109.

Note: For more information about associating terminals with devices, see the CA IDMS System Generation Guide.
