Extensions for Financial Services (XFS) interface specification Release 3.30 - Part 68: Text Terminal Unit Device Class Interface - Migration from Version 3.20 (CWA 16374) to Version 3.30 (this CWA) - Programmer's Reference

Scope

This document describes the migration that is necessary from Version 3.20 (CWA 16374) to Version 3.30 (this CWA).
This specification describes the functionality of the services provided by text terminal unit (TTU) services under XFS, by defining the service-specific commands that can be issued, using the WFSGetInfo, WFSAsyncGetInfo, WFSExecute and WFSAsyncExecute functions.
This section describes the functions provided by a generic Text Terminal Unit (TTU) service. A Text Terminal Unit is a text i/o device, which applies both to ATM operator panels and to displays incorporated in devices such as PIN pads and printers. This service allows for the following categories of functions:
• Forms oriented input and output
• Direct display output
• Keyboard input
• LED settings and control
All position indexes are zero based, where column zero, row zero is the top-leftmost position.
If the device has no shift key, the WFS_CMD_TTU_READ_FORM and WFS_CMD_TTU_READ commands will return only upper case letters. If the device has a shift key, these commands return upper and lower case letters as governed by the user's use of the shift key.
