Input
Because of the nature of operation of synchronous (block-mode) and NWA terminals, it might not be pos-
sible to support all or any of the Curses input functions. In particular, the following points should be
noted:
• Single-character input might not be possible. It may be necessary to press a special key to cause all
characters typed at the terminal to be transmitted to the host.
• It is sometimes not possible to disable echo. Character echo may be performed directly by the termi-
nal. On terminals that behave in this way, any Curses application that performs input should be
aware that any characters typed will appear on the screen at wherever the cursor is positioned.
This does not necessarily correspond to the position of the cursor in the window.
