Preparing Terminal and Workstation Users

This subsection provides information about using VT-series terminal emulators, VT

signal window commands, and function-key mapping.

Using VT Emulators

When using a VT-series terminal or VT-series terminal emulator without a keypad for

function keys, use the signal window for function key entry. If the emulator has a macro

capability, you can configure single keystroke macros to enter the key sequences to open

a signal window and specify the function key followed by the Enter key.

Host-Issued VT Signal Window Commands

A host application or a TACL macro can issue signal window commands, including the

KEYnnn commands which redefine the single keystroke invocations. To do this, the host

application must send the following exact sequence of characters:

This sequence of characters is followed by the signal window command and is

terminated by the first control character or by the 64-character maximum of the line 25

definition command (ESC o).

If a signal window happens to be open when the host sends this sequence, any keyboard

signal input is discarded and the window is closed at the terminal. The host signal

window command is processed and no indication or status is returned to the Tandem

application.
