property Scrollback : Boolean
Default: False
Defines whether the terminal is in scrollback mode.
If Scrollback is set to True, the terminal is placed into scrollback mode. In this mode, keystrokes are no longer translated into their terminal equivalents and instead serve to navigate through the scrollback buffer. Hence, in scrollback mode, the Page Up/Page Down keys will move the user through the scrollback buffer, as will the standard arrow keys.
If scrollback mode is activated, the terminal will also no longer receive data from the serial device. It is recommended that flow control is imposed on the COM port when the user switches into scrollback mode (either send an XOFF character or drop a hardware flow control signal), to help avoid the dispatcher's input buffer overflowing. The terminal does not do this itself. Imposing flow control helps keep the terminal data stable, which allows the user to navigate though the scrollback buffer in a profitable manner. Obviously, when the user leaves scrollback mode, the flow control condition would be ended to allow more data to come through and be processed.
