Selecting this check box causes each character typed at the keyboard to be
immediately displayed on the screen. When you're communicating with the host
computer (the Online check box in the Emulation tab of Terminal Setup is selected),
each character typed at the keyboard is transmitted to the host. Most host systems
(for example, a VAX running VMS) immediately send the same character back to
the terminal (that is, echo the character). The character is not displayed on
the screen until it is received back from the host.
When you're online and you select this check box, each character is sent two places: directly to display memory (the screen) and to the host computer. On an echoing host system, this means that each character you type appears twice on the screen. Select this check box only when communicating with host systems that do not echo each typed character, for example, some public networks.
This setting reflects the current terminal state of VT Local Echo, which can be
changed by the host. The associated default setting, saved with the model, is
VT Local Echo Default.
