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 controlAll 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.
