Line mode

When a character is typed it is first sent to the host application, then returned (echoed) back from the host application and finally displayed on the screen. The host application has full control of what is displayed on the screen. This is the default behavior for VT and ANSI emulations.

However, some host applications expect to receive the characters line by line instead (Line mode). In this mode the characters are displayed on the screen when typed, but the characters are not sent to the host until the Enter key has triggered a Line mode send. In fact, most control keys will trigger a Line send to the host application.

Line mode options

   Off       Default, Line mode is not used
   Basic     Line mode is on, every control character except the Backspace key will trigger a line mode send
   Extended  Line mode is on, every control character except the Backspace, Delete, Home, End, Cursor forward and Cursor back keys will trigger a Line mode send.

Please note that the Echo mode option should be checked even when Line mode is selected.

In Extended Line mode the listed keys will perform a local operation on the typed characters not yet sent. In the VT emulation, the Home function is on the Find toolbar button and Home key, the End function is on the Select toolbar button and End key, the Delete funtion is on the Remove toolbar button and Delete key.
