Erase() action

In 3270 mode, Erase deletes the character to the left of the cursor, shifting the field to the right of the cursor one position to the left, and replacing the last character of the field with a NUL character.

In NVT line mode, Erase performs an erase operation, removing the last character in the input buffer. In NVT character mode, it sends the Erase character to the host.
