It is possible to configure TellNext to send a DEL sequence (0x7F) when pressing the Backspace key.
In the sections:
Keyboard.EscapeSequences.VTXXX
Keyboard.EscapeSequences.ANSI
Change the behavior of the InternalCommand 104B (Backspace) as follows:
{
"Label": "FN_BKSP",
"InternalCommand": "104B",
"Data": "/08/20/08"
}
Change by
{
"Label": "FN_BKSP",
"InternalCommand": "104B",
"Data": "/7F"
}
The emulator will send DEL instead BS when pressing the BKSP key.
